Symptom guide / refrigerator
A refrigerator that makes a grinding, rattling or clicking noise
A noisy refrigerator is the one symptom where both Ontario companies behind this page start with sound rather than with a part: where the noise is loudest decides which fan is in question, and two of the usual causes cost nothing at all to rule out. The job here starts with a path rather than a part: the noise comes with the refrigerator no longer cooling properly - the GTA page states in its own words that food safety is at risk and that a technician should be called immediately rather than waiting to see if it improves [CA1]. That is why a refrigerator that makes a grinding, rattling or clicking noise belongs in the high-risk column before it belongs to any repair, and why the machine has to be unplugged before anything else is touched. The unit is not level, or it is vibrating against a surface is the first suspect — not priced [CA2], about 15 minutes — and the cheapest item on the list, condenser coils packed with dust, or the condenser fan blade fouled, sits at CA$80–CA$150 installed [CA2]. Owners describe it as a grinding or buzzing sound from inside the freezer, a rattle or loud hum from the back or the bottom of the fridge, a clicking sound every few minutes that never turns into cooling or a squeal or whine that is worst when the freezer door opens.

a grinding or buzzing sound from inside the freezera squeal or whine that is worst when the freezer door opens
The London page calls the evaporator fan the most common source of a grinding or buzzing noise and gives the reason: frost builds where it should not and the fan blade clips it on every rotation, which produces a rhythmic grind, while a worn fan motor bearing makes a drier, more constant sound. It publishes a thirty-second test a technician runs first: open the freezer door and press the light switch in with a finger to keep the refrigerator thinking the door is closed, and if the grinding gets louder or changes pitch the evaporator fan is almost certainly involved. The GTA page prices the same repair at CA$130-230 fitted and attributes a persistent high-pitched squeal or whine from inside the freezer to the evaporator fan bearing. The London page's own warning is the reason this cause is not a wait-and-see: grinding paired with food in the fresh-food section going warm means cold air is not circulating, and it tells the reader to move perishables to a cooler and book a repair. Time basis: neither page publishes a duration, so 60 minutes is a book estimate.
no part-only price is claimed: the GTA page prices this repair as a fitted total rather than as a part, and the London page prices it as a fitted total as well, so the installed price is the published figure and no part price is invented here.
medium likelihoodadvancedCA$200–CA$400 installedabout 60 min
a rattle or loud hum from the back or the bottom of the fridge
The GTA page attributes a rattling or loud humming from the refrigerator to the condenser fan motor and prices the replacement at CA$120-220 fitted. The London page prices the same fan motor replacement at CA$200-400 and lists it in its technician group. The London page's locating test is free and decides between the two fans: if the grinding is louder from behind or underneath the refrigerator the source is at the back, and if it is louder inside the freezer it is inside that compartment. Time basis: neither page publishes a duration, so 60 minutes is a book estimate.
no part-only price is claimed: both pages publish this repair as a fitted total rather than as a part, so the installed price is the published figure.
defrost system fault, with ice that the fan then clips [CA2]
medium likelihoodadvancedCA$250–CA$500 installedabout 75 min
a grinding or buzzing sound from inside the freezer
The London page lists a defrost system repair as the fix when ice is causing the noise, at CA$250-500, and publishes the free tell that separates this fault from a worn fan: listen after a defrost, because if the grind only appears for a while after the freezer self-defrosts, the timing points toward the defrost system rather than the fan. The London page also lists repeated icing that comes back after a manual defrost among the conditions that need a technician rather than a homeowner. The GTA page's separate guide to this fault, cited on this site's not-cooling page, gives the mechanism: frost builds until the fan can no longer pull air through the coil. Time basis: neither page publishes a duration, so 75 minutes is a book estimate.
no part-only price is claimed: the London page prices the defrost repair as a job at CA$250-500 and publishes no part row for it, so the installed price stands alone.
medium likelihoodadvancedCA$180–CA$400 installedabout 60 min
a rattle or loud hum from the back or the bottom of the fridgea clicking sound every few minutes that never turns into cooling
The London page prices an ice maker or inlet valve repair at CA$180-400 and puts it in the technician group. The GTA page prices the ice maker assembly at CA$150-300 and a water inlet valve at CA$100-200, and describes the noise this cause makes in its own words: knocking inside the cabinet near the top of the freezer or from the back, where the ice maker arm can knock against ice in the collection bin or cubes dropping from the tray sound like a sharp knock. The GTA page also says that gurgling and bubbling sounds are normal, being refrigerant flowing and equalising, and that no action is needed for them, which is why this page does not send every noise to a technician. Time basis: neither page publishes a duration, so 60 minutes is a book estimate.
no part-only price is claimed: both pages publish these repairs as fitted totals rather than as parts, so the installed price is the published figure.
compressor wear (internal parts or failing mounts) [CA2]
low likelihoodadvancedCA$500–CA$1,200 installedabout 150 min
a rattle or loud hum from the back or the bottom of the fridge
The London page prices compressor repair or replacement at CA$500-1,200 or more, marks it as specialist work, and describes the sound: the compressor is the sealed motor that pumps refrigerant, a healthy one hums, and one that grinds, knocks or rattles loudly can signal worn internal parts or failing mounts. The GTA page prices a compressor replacement at CA$300-600 or more and describes the clicking pattern that accompanies a compressor failing to start. The London page's own decisive line for this cause is the one that puts it out of the do-it-yourself group: compressor work is a sealed-system repair that needs a qualified technician and, in many cases, makes the household weigh repair against replacement. Time basis: neither page publishes a duration, so 150 minutes is a book estimate.
no part-only price is claimed: both pages price compressor work as a fitted or specialist total, and the London page describes the compressor as a sealed-system component that needs a qualified technician, so a part price alone would misrepresent the job.
Repair or replace?
The verdict
The London page's rule turns on age and on the size of the repair: a grinding noise on a refrigerator under about eight years old is usually worth repairing, because the appliance has plenty of life left, while on a unit pushing fifteen years a major repair like a compressor is harder to justify against the cost of a new, more efficient model, and age, the price of the specific repair and how well the refrigerator has performed otherwise should all factor into the decision. The GTA page reaches the same place from its own table: a start relay, a coil clean or a fan motor is inexpensive against a refrigerator that cost well over a thousand, while a compressor at CA$300-600 or more is often not cost-effective on an older unit. Both pages put one condition ahead of the arithmetic, and this page does too: if the noise comes with the refrigerator no longer cooling properly, the machine stops being a repair decision and becomes a food-safety one. [CA1]
Neither Ontario company publishes a job count for this complaint, so no median and no sample size appears on this page for either of them, and no completed-invoice dataset is quoted here: the only frequency statement on either page is a share with a stated scope, in the GTA page's own words, that heavily clogged coils account for roughly 30 percent of the loud-fridge service calls that company takes. A share of one company's own calls is not a count of jobs and is not turned into one here, and no conversion from a United States dataset is printed on this page either, because no publisher of completed refrigerator invoices cited here breaks its records down by this complaint.
Neither Ontario page publishes a replacement price, so this page prints none and computes no break-even line against a new unit; what it prints is the two companies' published rules, one against the age of the machine and one against the size of the repair. The replacement side of that comparison has moved in Canada in 2026 for a reason that appears in neither company's price list: the counter-tariff measure in effect since 8 September 2026 runs 15 to 50 percent on approximately US$28 billion of imports from the United States, with appliances named in the source's own list of affected goods, which raises the price of a replacement rather than the price of a repair. The repair side is priced in Canadian dollars by both companies and is not converted here.
the London page publishes the life of the machine in its own words: most refrigerators last between ten and fifteen years, though that varies with brand, use and maintenance. This page plans from the bottom of that published range, ten years, because the same page's own decision lines sit lower still, at about eight years for a repair that is usually worth doing and at fifteen years for a unit where a major repair is hard to justify; planning from the lower bound of the publisher's own range does not overstate the case for repairing an older machine. The choice of the lower bound is an editorial decision recorded here rather than in the fact fields.

a rattle or loud hum from the back or the bottom of the fridge
The London page publishes three no-tools checks that solve a surprising number of noisy fridges in its own words: level the unit, because one that rocks slightly can buzz and rattle; check for contact, because a refrigerator touching a wall, a cabinet or a water line can amplify a small vibration into a loud rattle; and reseat the drip pan, because a loose pan underneath can rattle. The page puts all three before any call to a technician. Time basis: the page publishes no duration, so 15 minutes is a book estimate for the three checks together.
no part is involved: the London page lists this as a free check the owner runs with no tools, so no part price and no installed price is claimed for it.
condenser coils packed with dust, or the condenser fan blade fouled [CA2]
high likelihoodeasyCA$80–CA$150 installedabout 30 min
a rattle or loud hum from the back or the bottom of the fridge
The London page puts the clean in its own table as often a free do-it-yourself job and says to unplug the refrigerator, pull the lower rear or front grille, and vacuum the dust from the coils and the fan twice a year. The GTA page publishes the strongest frequency statement on either page, in its own words and with its own stated scope: heavily clogged coils account for roughly 30 percent of the loud-fridge service calls that company takes, and they can be resolved without a technician. The London page's grille-and-vacuum description is the same job. Time basis: the GTA page publishes no duration for the clean, so 30 minutes is a book estimate.
no part is involved: on both pages this is a clean rather than a replacement. The GTA page prices the professional clean at CA$80-150, and the London page lists the same work as often a free do-it-yourself clean, so this cause carries an installed price and no part price.
a clicking sound every few minutes that never turns into cooling
The GTA page puts a start relay at CA$15-40 for most models and the fitted repair at CA$80-150, and publishes the free test the owner can run: unplug the refrigerator, remove the relay from the compressor at the back, and shake it, because a relay that rattles has a broken internal component and needs replacement. The page states the stakes in its own words: continuing to let the compressor attempt to start without a working relay will eventually burn out the compressor motor. The London page does not price this part on its noise page and lists electrical components among the work it says is not a do-it-yourself project, so the two pages differ on how far the owner should go and this page shows both positions rather than choosing silently. Time basis: neither page publishes a duration, so 30 minutes is a book estimate.
