Symptom guide / freezer
The freezer is warm inside while everything sounds like it is running
The repair that gets mistaken for the expensive one: a stopped evaporator fan makes a freezer run, warm and frost up exactly like a dying compressor, and the free check is to stand in front of it and listen for airflow before anyone prices a $700 sealed system. The free fix on this list is the slow one: about 30 minutes of work on dust and pet hair packing the condenser fan, no part needed [S1], and 1 of the 5 causes here sits in that same column. On a freezer the complaint is the freezer is warm inside while everything sounds like it is running, and it arrives in these words: it is warm inside but the motor keeps running, there is no airflow and no sound from inside, a chirp or click that stops when I open the door, ice is building up behind the rear panel or the back or the underside is hot to the hand. Money enters the page only after those: the completed repairs behind this symptom run $342–$470 [S1].

The failure behind most of these calls, and the reason the page exists: the most common thing opened is not a worn motor but a blade jammed or struck by frost, and the motor then stalls, draws current and burns out. The source's distinction is that the ice did not come from nowhere - a defrost fault or a door seal let the humidity in - which is why jobs coded to a frost complaint run $425 rather than $380: there is ice to clear and a second fault to find, not just a part to fit. Fitting a new fan into a compartment full of ice fixes the machine for a few weeks.
S1 publishes no part-only price; it prices the completed evaporator fan repair at a $380 median across 48 jobs, and the noise-coded jobs at a $476 median where ice also has to be cleared

a chirp or click that stops when I open the doorthere is no airflow and no sound from inside
The ordinary end of a motor that runs more or less continuously for a decade, and the one with a free tell built into the machine: on most models the door switch cuts power to the evaporator fan, so a noise that stops the instant the door opens is almost always that fan. The classic warning is a chirp or a rhythmic click that changes when the door opens, which is a bearing rather than a blade - the two sound different and only one of them comes with ice.

a defrost fault or a frozen drain re-icing the coil [S1]

ice is building up behind the rear panelthere is no airflow and no sound from inside
The second fault that decides whether the repair comes back, and the reason the source's answer to 'will a new fan fix it for good' is a conditional: if the evaporator was iced, something let moisture in or stopped it being removed, and there are only three candidates - a defrost heater or timer that is no longer running its cycle, a door seal that no longer seals, or a drain that has frozen so the meltwater refreezes on the coil. Each has its own repair and any of them will kill the new fan the way it killed the last one.
no separate defrost figure is published here; S1 prices the fan job it accompanies at a $425 median when the call is coded to frost build-up, against $380 for the fan alone

The row that argues for a meter rather than a part: on units with a variable-speed or electronically commutated fan the motor is commanded by the board, so a fan that does not run has at least two possible owners and the diagnosis is electrical before it is mechanical. It is also the row that keeps this page honest about the compressor question - the source's own framing is that spending $396 to find out is the right order of operations against a $700 compressor job, and that order only holds if the cheap possibilities are actually tested rather than swapped.
S1 publishes no board or motor-command figure for freezers; the motor it does price is the $380 evaporator fan job, and the point of the row is that a fan which does not run is not always a fan that has failed
Repair or replace?
The verdict
Listen before you price anything. A frost free freezer should have audible airflow inside, and silence in a running freezer points at the evaporator fan; a warm week with a hot back points at the condenser fan; ice behind the rear panel means the fan question comes with a defrost question. Then repair rather than replace - at a $396 median a fan motor is not a decision on any freezer worth keeping, and it is a part with a service life, not a sign the machine is finished. The one judgement call is a machine that needs a fan, a defrost heater and a door gasket at once: three repairs together on an old freestanding freezer approach the value of the appliance, and that is the moment to price replacement rather than fit the first part.

Planning life used for the decision: 12 years
The headline band and the 136-job count come from the fan page: its own 136 completed freezer fan repairs at a $396 median with the middle half at $342-470. The control board, defrost heater and $381 evaporator-fan bands are the other source's part-level cuts of its separate 2,272-job freezer book - a control board at $494 across 51 jobs, a defrost heater at $374 across 15 and an evaporator fan at $381 across 43, each with its own middle half - and the fan page publishes none of those three rows itself. The remaining band is the fan page's own cut of the same 136-job dataset behind the headline: an evaporator fan at a $380 median across 48 jobs, with no middle half published for that row. Two pages, two evaporator-fan numbers - $380 across 48 and $381 across 43 - stand beside each other as each source publishes them and are never added together or averaged. 2026-10-13: S1 median $380 across 48 jobs, S2 median $381 across 43 jobs.
The break-even is between two repairs rather than between a repair and a machine: $396 against a $700 compressor job, on a freezer where the compressor replacement is the diagnosis this fault is routinely mistaken for. That is also the argument for doing the checks in order - the source's phrasing is that spending $396 to find out is the right order of operations, and the cost of getting the order wrong is not only money: a compressor that keeps cycling against a fault is how a $396 repair becomes a $700 one, which is why the safe-check list ends with not leaving it running warm for days.
the same twelve-year planning line used in this site's other freezer guide, with the fan treated as a component with a clear service life rather than as evidence the appliance is finished: S1's own repair-or-replace position is repair in nearly every case, and the judgement only changes where a fan, a defrost heater and a door gasket arrive together on an old freestanding unit

The one genuinely preventable failure on the page, and the only free one: the condenser fan lives in the dirtiest air in the house, at floor level, and its job is to blow room air across the condenser coil to dump the heat the system removed. Coils and blades pack with dust, the motor works harder against that load and against its own heat, and fails early. Cleaning it costs nothing, occasionally fixes a warm freezer outright, and is the reason the source's safe-check list ends on the coil - while a condenser failure is also the quieter one, showing up as a freezer that loses temperature over a week with a hot back rather than a freezer that goes silent.

S1's fan page publishes no defrost-heater or control-board row at all, so neither count is carried on a cause on this page. Its compressor row ($750 across 108 jobs) is not used, because S1 prices the same part at $700 across 107 - the two pages disagree and the record prints only the fan page's figure
