Direct answer: If your Whirlpool freezer is clicking but not cooling, the first thing to sort out is where the click is coming from. A click every few minutes with little or no hum usually points to the compressor trying and failing to start. A rapid tick or knock from inside the cabinet leans more toward an evaporator fan hitting ice or a heavy frost problem choking airflow.
Most likely: Most often, this turns out to be a failed freezer compressor start relay, a frost-packed evaporator area, or dirty condenser coils making the sealed system run hot and struggle.
Start with power, temperature setting, door seal, and the exact click location. Then check for back-wall frost, fan movement, and dirty coils. Reality check: a freezer that is truly warm and clicking is usually not a small calibration issue. Common wrong move: unplugging it for hours, plugging it back in, hearing one normal-sounding hum, and assuming the problem fixed itself.
Don’t start with: Do not start by ordering a control board or compressor. Those are expensive guesses, and the sound pattern plus a few visual checks usually narrows this down fast.
You hear a click near the compressor area, maybe a short hum, then silence. The cabinet stays warm or only slightly cools.
Start here: Start at the rear lower section with coil cleaning and compressor-start checks.
The sound seems to come from behind the back interior panel, often with frost or uneven cooling.
Start here: Start by looking for frost buildup and an evaporator fan blade rubbing ice.
There may be snow-like frost on food packages, the back wall, or around vents, and airflow feels weak.
Start here: Start with a frost and airflow check before assuming a bad compressor.
The side walls or compressor area feel hotter than normal, and the unit struggles to restart.
Start here: Start with condenser coil cleaning, room clearance, and compressor-overheat clues.
This is the classic pattern when the compressor tries to start, clicks, then drops out without cooling. The click usually comes from the back near the compressor.
Quick check: Listen at the rear lower compartment. If you hear a click every few minutes and the compressor gets hot but never settles into a steady hum, the start relay is high on the list.
A freezer can click or tick when the fan blade hits ice, and it will stop cooling well because cold air cannot move through the cabinet.
Quick check: Open the freezer and look for frost on the back interior wall, around vents, or packed around the fan area.
When the coils are matted with dust, the compressor runs hotter and may trip off on overload, especially on an older or already weak start circuit.
Quick check: Pull the unit out and inspect the lower rear or bottom coil area for lint, pet hair, and dust mats.
If the compressor runs but the freezer stays warm and the sound is from inside the cabinet, the fan may be stalled, noisy, or dead.
Quick check: With the door switch held closed, listen for the interior fan. If the compressor is running but you get no fan sound and no airflow, the fan is suspect.
Rear-compartment clicking and inside-cabinet clicking lead to different repairs. You can waste a lot of time if you lump them together.
Next move: You now know whether to focus on the compressor area or the evaporator fan and frost area. If you cannot tell where the sound is coming from, move to the visual checks next and use frost and heat clues to narrow it down.
What to conclude: A rear click usually points to a compressor start problem or overheating. An inside click or tick usually points to fan interference or frost buildup.
A freezer with a frost-packed evaporator can sound mechanical even when the real problem is airflow. This is one of the most common lookalikes.
Next move: If frost is light and the gasket reseals well, cooling may recover after airflow is restored and the unit runs for several hours. If the back wall is heavily frosted or the fan area looks iced in, keep going toward the fan and defrost branch rather than buying a compressor part first.
What to conclude: Heavy frost on the back wall points away from a simple thermostat issue and toward an evaporator fan obstruction or defrost failure. A torn gasket can feed that frost problem.
Dirty coils are a safe first fix and they can make a marginal start circuit act much worse. This is especially worth doing if the freezer sides or compressor area feel unusually hot.
Next move: If the compressor starts and stays running with a steady hum, let the freezer cool for 12 to 24 hours and monitor temperature. If it still clicks off from the rear after cleaning, move to the compressor-start check. If the click is inside the cabinet, move to the fan check instead.
By this point, the two main DIY-capable paths are usually clear: the compressor is failing to start, or the evaporator fan is blocked or dead.
Next move: A clearly burned or rattling relay supports replacing the freezer compressor start relay. A fan blade hitting ice or a dead fan motor supports the evaporator fan repair path. If the relay looks normal but the compressor still only clicks and gets very hot, or if the fan area is clear but cooling is still poor, the problem may be beyond a simple DIY repair.
Once the sound pattern and physical clues line up, the next move should be decisive. Guessing past this point usually means wasted money.
A good result: A good repair will give you steady compressor operation, normal airflow, and freezer temperature trending back toward 0°F instead of repeated clicking with little cooling.
If not: If a new start relay does not get the compressor running, or the compressor runs but the freezer still barely cools, stop buying parts and schedule service for sealed-system or control diagnosis.
What to conclude: At this stage, the remaining non-DIY possibilities are a weak or locked compressor, a refrigerant problem, or a less-common control issue. Those are not good guess-and-buy repairs for homeowners.

That pattern usually means the compressor is trying to start and failing, often because of a bad freezer compressor start relay or an overheated compressor. If the click is from inside the cabinet instead, look harder at frost buildup or an evaporator fan problem.
Yes. Dirty freezer condenser coils make the compressor run hot and can push a weak start circuit over the edge. Coil cleaning is not a cure for every case, but it is one of the first things worth doing because it is safe, common, and sometimes enough to get the unit running again.
If the compressor is running with a steady hum but you have little or no airflow inside the freezer, the evaporator fan is the better suspect. If you hear scraping or ticking from inside and see frost on the back wall, the fan may be hitting ice.
Not first. On this symptom, a control board is a much less certain guess than a failed start relay, frost-blocked airflow, dirty coils, or a bad evaporator fan. Get the sound location and frost pattern straight before spending money on electronics.
If a correct replacement relay does not change the rear click-and-no-cool pattern, the compressor itself may be weak or locked, or there may be a sealed-system problem. That is the point to stop buying parts and call for service.
Usually not by itself, but a leaking freezer door gasket can feed heavy frost buildup. That frost can block airflow or jam the evaporator fan, which can create clicking, ticking, or knocking sounds from inside the cabinet.
