Controller burned out

There are a few potential causes of a noisy bottom freezer. Here are some things you can try to fix the problem:

1. Check for frost buildup: Frost buildup can cause the freezer to become louder as it has to work harder to keep things frozen. To check for frost buildup, remove all items from the freezer and unplug the fridge. Then, use a hair dryer to melt any frost that has accumulated on the evaporator coils (usually located behind the back panel of the freezer).
2. Check for loose parts: Some common sources of noise in a freezer are loose screws, washers, or other small parts. Check for any loose items and tighten them as needed.
3. Check the evaporator fan: The evaporator fan is responsible for circulating air within the freezer. If the fan is not working properly, it can cause the freezer to become noisy. You can check the fan by removing the back panel of the freezer and listening for any unusual noises. If you suspect the fan is the problem, you may need to replace it.
4. Check the compressor: The compressor is responsible for circulating refrigerant and cooling the freezer. If the compressor is malfunctioning, it can cause the freezer to become noisy. You can check the compressor by listening for any unusual noises or by checking the compressor with a multimeter. If you suspect the compressor is the problem, you may need to replace it.

If you are unable to fix the problem yourself, you may want to consider contacting a repair service. They will be able to diagnose and fix the issue more accurately.

There is probably a safety device of some description incorporated into the design though it probably isn't to blame for the trouble.

You need to discover whether it is the fan, compressor or both; neither should run constantly. The condenser fan is only needed while the compressor is pushing the refrigerant around the circuit and in many designs, where a belt driven compressor is used it is usual for the fan to be mounted on the extended motor shaft so they can't run independently.

If the compressor runs constantly and the cabinet doesn't suffer from excessive freezing it is almost certain either the compressor is failing or there is a leak and refrigerant is being lost - probably the latter.

Hello;

My name is Peter. I am a retired field service refrigeration technician.

Your problem is not your thermostat. In some models the compressor knocks out the overload relay. They relay could last a few seconds or a few weeks before the compressor knocks it out again. This is especially turn with the LG units.

You will need a multi-meter to check your compressor.

1.) Unplug your unit. Remove the bottom back cover.

2.) Remove the overload components to expose the 3 pins on the compressor.

3.) Inspect the pins on the compressor. Are they clean or are they damaged from heat (Steel melting).

4.) With your multi-meter, set the meter on the lowest Ohms. Read the Ohms between each of the pins. You will have 3 readings. One reading will be high and the other 2 readings will be lower. Add the 2 lower readings together. This value must equal the high reading within a few tenths.

I hope I am wrong. A new compressor depending on the model is $275-$450.00. Include a system filter for $40.00, plus new refrigerant $45.00 and the cost od an experienced technician $300.00.

your freezer might be having blockage on the drain pipe thus not allowing water to flow on the drain tray if the drain tray is mounted on the compressor and its dry then the compressor or the condensor pipes are burning the drain tray. the solution to this problem is to service your freezer

How is temperature controlled, refrigerant pressure? Thermostat? Does the top of the compressor get too hot to touch?

COOLING

Dust on the condenser coils can cause overheating, observe safety precautions then clean coils. Switch off the unit before you clean them. If the problem persists, test the compressor for overheating. Overheating will cause many problems with cooling ability. Leave the unit unplugged for 3 hours and plug it in again. If it starts working, the compressor is probably overheating (Observe cautions with food going bad). A simple cause of the problem might also be that there is not enough airflow Lack of airflow is the number one cause of compressor problems and thus an owner purchasing another unit for hundreds of dollars when you can fix it for free.There should be at least several inches distance between the sides and walls/cupboards/ceiling.

Electrical

There is an in-line fuse mounted in the line supplying the power to the ice-maker. It is in the wire clipped to the side, change out this fuse asap. It is actually a 20-amp fused, associated with the grounded electrical supply.

TIME TO CHANGE YOUR FILTER

While your on the back of the system, please check the filter. There is a filter in the back of the fridge in the upper right hand side. If you do not change it, it will slow down the frig and burn it out permanently.

The most common problem is low refrigerant (freon). If you don't have gauges to check the pressure of your refrigerant, do this: the compressor has one small line running to the coils on the top of the freezer. That small line should be hot enough to burn your finger if you touch it when the compressor is running. Also the big copper tube running into the compressor should be cold to the touch, almost freezing. If not you are probably low on refrigerant. Without gauges and the ability to buy freon, you will need to hire a refrigeration repair service to find the leak in your system, repair it and then gas it up. But there are a couple of other things to check first. Near the compressor is a radiator like set of coils in front of a fan. If the compressor is running that fan should be running too. if not, the unit won't cool. Also the radiator coils may be covered with dust or grease. You must have a good flow of air through these coils to dissapate the heat put out by the compressor.If it is stopped up, brush the dust from the front of the coils. Look inside the freezer as well and make sure the inside coils are not frozen over. Is so unplug the unit and let the frost melt off. If that is happening you may need a new timer on your drfrost system.

Compressor is bad the clicking noise is the Start Relay/Overload is kicking on and off. compressor is warm because it's trying to start but can't Frigidaire is known for bad compressors. I don't think the Start Relay/Overload is bad because the compressor gets warm.

Set the thermostat to the coldest and check if there's power to the compresor relay , if yes the relay or the compresor are bad (in this case replace the relay which is the cheaper first step ,but if the compresor still won't start probably is burned out) If there isn't power to the compresor put a jumper wire to the thermostat if the compresor runs replace the thermostat.

i dont think so i would look at the compressor kicking out on thermal overload or a faulty thermostat thermostats have two settings cut in cut out your cut in could be bad and not turning the compressor on till the temp reaches melting temps now if your hearing a click buzz then you need to look at the compressor and make sure the compressor fan is running but its not a defrost promblem
