Direct answer: If your Insignia freezer is clicking but not cooling, the most common homeowner-level causes are a stalled compressor trying to start, heavy frost choking airflow, dirty condenser coils, or an evaporator fan that is not moving cold air. Start with the simple visual checks before you assume the sealed system is bad.
Most likely: A repeated click every few minutes with little or no cooling often means the compressor is trying to start and dropping back out, but a freezer packed with frost or blocked airflow can sound similar from the outside.
Listen for where the click comes from, look for frost on the inside back wall, and check whether the compressor is hot, humming, or completely quiet between clicks. Reality check: once a freezer has been warm for hours, food safety becomes part of the job too. Common wrong move: scraping ice off the back panel with a knife and puncturing the liner or coil.
Don’t start with: Do not start by ordering a compressor, control board, or random relay kit. First figure out whether the clicking is coming from the compressor area, the inside fan area, or a frost-packed back panel.
You hear a click near the compressor area, maybe a short hum, then silence. The cabinet stays warm or only slightly cool.
Start here: Start with condenser cleaning, compressor temperature, and startup behavior.
The freezer may run, but air movement is weak and frost or snow builds on the rear interior panel.
Start here: Start with the frost and airflow checks before chasing electrical parts.
The light may work, but you do not hear the normal inside circulation fan when the door switch is held closed.
Start here: Check for frost blockage around the evaporator area and whether the evaporator fan is stalled.
The freezer was recently unplugged, tilted, or restarted after losing power, and now it clicks without getting cold.
Start here: Let it sit level if it was moved, then verify outlet power and watch for a failed compressor start attempt.
A warm freezer with a click from the lower rear every few minutes is classic compressor start trouble. You may hear a brief hum, then a click as it drops out.
Quick check: Pull the freezer out, remove the lower rear cover if accessible, and listen near the compressor. If the compressor gets very hot and never settles into a steady run, this is a strong fit.
A freezer can click normally from controls or relays while the real problem is that the evaporator is buried in frost and cold air cannot circulate.
Quick check: Open the door and inspect the inside back wall. A thick white frost blanket or bulging frost pattern points to a defrost-side problem.
Dust-packed coils make the compressor run hot and struggle. On some units that leads to repeated hot restart attempts and clicking.
Quick check: Look underneath or behind the freezer for a mat of lint and pet hair on the condenser area.
If the cooling system is making some cold but the inside fan is not pushing it through the cabinet, the freezer can stay warm and sound odd or intermittent.
Quick check: Hold the door switch closed and listen for the evaporator fan. If the compressor area is active but the cabinet is quiet inside, check this branch next.
Rear-bottom clicking and inside-cabinet clicking lead to different fixes. You save time by separating those early.
Next move: If you clearly identify the sound source, the next checks get much narrower and more useful. If you cannot tell where the click is coming from, move to the visual checks next and use frost pattern and compressor heat as your guide.
What to conclude: A rear-bottom click usually points toward compressor startup trouble or overheating. A frosted back wall or dead inside fan points toward airflow and defrost trouble.
A freezer that cannot breathe will act sick even when the sealed system is still okay.
Next move: If the clicking settles down and cooling starts improving over the next several hours, the problem was likely overheating or airflow restriction. If it still clicks and stays warm, move on to frost pattern and compressor behavior.
What to conclude: Blocked vents, a leaking gasket, or dirty condenser coils can keep temperatures up and make the compressor short-cycle or overheat.
A heavily frosted evaporator is one of the most common lookalikes for a bad compressor because the freezer gets warm even though parts of the system still run.
Next move: If the freezer cools normally again after a full defrost, the main problem is likely in the freezer defrost system rather than the compressor itself. If there was no heavy frost, or it still clicks and does not cool after defrosting, keep going to the compressor check.
This is the cleanest homeowner clue for a bad start attempt versus a freezer that is simply not being asked to cool properly.
Next move: If it starts and stays running after cooling down and coil cleaning, overheating was likely part of the problem, though a weak start device may still be near the end. If it keeps humming briefly and clicking off, the strongest DIY-supported part branch is the freezer compressor start relay and overload. If a new start device does not change anything, stop there and call for service.
By now you should know whether you are dealing with airflow frost trouble, a dead evaporator fan, or a compressor start problem.
A good result: A successful repair gives you steady compressor operation, normal inside airflow, and a clear drop in cabinet temperature over the next several hours.
If not: If none of these branches restore cooling, the remaining likely causes are sealed-system loss, compressor failure, or a control issue that is not a smart guess-buy.
What to conclude: This is where you either make a supported part repair or stop before spending money on low-odds parts.

That pattern usually means the compressor is trying to start and failing, often because of overheating or a bad external start device. It can also happen when heavy frost or poor airflow keeps the freezer from cooling properly, so check the back wall frost and condenser condition first.
Yes. If the condenser is packed with dust, the compressor can run too hot and struggle to restart. Cleaning the condenser area is one of the first checks because it is common, safe, and sometimes enough to get the freezer cooling again.
That strongly suggests a defrost-side problem or airflow blockage rather than an immediate compressor failure. If cooling returns after a full thaw and then frost builds back on the inside rear panel, look at the freezer defrost system and evaporator airflow.
Only if the clues support it. The best fit is a compressor that hums briefly, clicks off, and repeats that pattern from the lower rear, especially after you have already ruled out heavy frost and dirty condenser issues. If the compressor runs steadily, a start relay is probably not your problem.
Stop when you see oily residue, a small uneven frost patch, breaker trips, burnt wiring, or a compressor that still will not run after the supported start-device check. Those signs point toward sealed-system, compressor, or deeper electrical diagnosis that is better handled by a qualified appliance tech.
