Direct answer: If your Midea chest freezer clicks but will not start, the most common causes are a weak power supply, an overheated compressor area, or a failed freezer compressor start relay/overload. If it clicks every few minutes and the compressor never settles into a steady hum, do the basic power and airflow checks before you buy anything.
Most likely: Most often, you will find either a loose power connection, a hot dusty compressor compartment, or a freezer compressor start relay that has failed and is only letting the compressor try and trip out.
First separate a true no-start from a freezer that is running but not cooling well. On a chest freezer, a single click followed by silence is different from a steady hum, fan noise, or interior light behavior on other appliances. Reality check: when a compressor is failing to start, the sound pattern matters more than the brand name. Common wrong move: plugging the freezer into a light-duty extension cord and then chasing parts.
Don’t start with: Do not start by ordering a compressor or a control board. A simple outlet issue or bad freezer compressor start relay is far more common than a sealed-system failure.
You hear one click from the lower rear area, but there is no steady compressor hum and the freezer stays warm.
Start here: Start with the outlet, plug, and cord fit, then check whether the compressor shell is unusually hot.
Every few minutes you hear a click or short buzz, then it drops out again without starting.
Start here: This pattern strongly points to the freezer compressor start relay/overload or a compressor that is struggling to start.
The freezer may run briefly after sitting unplugged, but later goes back to clicking and not starting.
Start here: Look for poor airflow around the compressor area, dust buildup, or a start device that fails once it heats up.
The freezer clicked but would not start after being relocated, cleaned, or plugged into a different outlet.
Start here: Check for a loose plug, damaged cord, tipped-unit settling time, and a start relay that may have been jarred loose or weakened.
A compressor needs a solid power feed to start. Loose plugs, shared circuits, extension cords, or a weak outlet can let it click but not get moving.
Quick check: Plug the freezer directly into a known-good wall outlet and make sure the plug blades fit tightly with no wobble or heat marks.
If the compressor runs hot, the overload protector can click off before the motor gets going. This is common when the rear lower area is packed with dust or pushed too tight to the wall.
Quick check: Unplug the freezer and feel near the compressor area after it cools a bit. Heavy dust, trapped pet hair, or very tight clearance supports this cause.
This is the classic click-no-start part failure. The relay tries to kick the compressor on, then the overload opens when it cannot get up to speed.
Quick check: After unplugging the freezer, inspect the start device on the compressor terminals. A burnt smell, rattling pieces, or heat damage is a strong clue.
If power is good and a known-good start device still only produces clicking or a brief buzz, the compressor itself may be seized or internally damaged.
Quick check: The compressor gets very hot, tries to start, then trips out again even after the simple checks and start-device inspection.
A chest freezer that clicks but never develops a steady hum is a different problem than one that runs and just is not cold enough.
Next move: If you hear a steady hum and the cabinet starts cooling, you are not dealing with a true no-start. Watch temperatures and airflow instead. If all you get is clicking or a short buzz with no steady run sound, keep going with power and compressor-start checks.
What to conclude: This narrows the problem to startup power, the start device, or the compressor itself rather than a simple temperature-setting issue.
Bad outlets and weak connections waste a lot of time because they can mimic a bad compressor start relay.
Next move: If the freezer starts and settles into a steady hum on a proper outlet, the problem was likely the original power source or connection. If it still clicks but will not start on a known-good outlet, move on to heat and airflow around the compressor area.
What to conclude: You have either ruled out the house-side power issue or found it before buying freezer parts you did not need.
A hot compressor will trip its overload and click off. Dust and tight clearance make that much more likely.
Next move: If it starts after cooling and cleaning, poor airflow or heat buildup was likely the trigger. Keep monitoring over the next day. If it goes right back to clicking or buzzing without starting, the start device is now the leading suspect.
On this symptom, the start relay and overload are the most common freezer-side parts to fail before the compressor itself.
Next move: If re-seating a loose connection restores normal startup, keep the freezer running and monitor it closely for the next 24 hours. If the relay shows heat damage, rattles, or the freezer still only clicks, replacement of the freezer compressor start relay is the most supported next repair.
At this point you have done the low-risk checks. The next move should be based on what the compressor and start device actually told you.
A good result: A successful start and stable cooling after relay replacement confirms the start device was the failed part.
If not: If the clicking remains with good power and a fresh start device, the compressor is the likely failure and that is usually not a basic DIY repair.
What to conclude: You either finished the practical repair or reached the point where further DIY part swapping is unlikely to pay off.

That sound usually comes from the compressor trying to start and then dropping out. The most common reasons are weak power at the outlet, an overheated compressor area, or a failed freezer compressor start relay.
Yes. A loose or weak outlet can let the freezer get enough power to click but not enough to start the compressor properly. That is why a direct test on a known-good wall outlet comes before parts.
A bad relay often smells burnt, shows melted plastic, or rattles when removed because the internal pieces have broken apart. The freezer will usually click every few minutes without settling into a steady hum.
If power is good and a correct new start relay does not change the symptom, the compressor is the likely problem. At that point, further repair usually means a pro diagnosis rather than more guess-and-buy parts.
No. Repeated restart attempts can keep overheating the compressor and overload. Let it cool, do the simple checks once, and then make the next move based on what you found.
Yes. A move can leave the unit needing upright settling time, loosen a weak connection, or finish off an already failing start relay. If it was tipped, let it sit upright for several hours before testing.
