Frigidaire commercial freezer not cooling.

bulmer...it takes about two days to fully defrost these units unless you take the freezer section cover off and use a heat source. If you do...be sure to protect yourself against water and electricity mixing....not healthy. See below for another note.

clean the condenser coils below the unit.

check for the amount of gas in the unit. It must be off for half an hour. Remove the back fiber panel. The big thing is the compressor. Clean off the largest pipe coming out of it. Plug the unit in...watch out for the fan! The pipe should frost up and then clear off or stay wet after about 5 minutes. It should not be frosty. If it is, you need refrigerant.

Note: If you do remove the inside freezer panel and defrost, you can see how much refrigerant you have in your unit. Start the unit. Wait 5 minutes and observe the coils. They should be evenly frosted end to end. If approximately so, you're good. If not, you're low on gas.

It is the compressor that has failed. The hum is it trying to start and the following click is the overload protector opening. What is the temperature where the refrigerator is located? Allow the compressor to cool down before trying to restart it. If it still does not restart after it has cooled off it is done.

it should not be the compressor as the bottom is only not cooling.

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.
