Maximum temperature alarm, Outputs unchanged. I think your board needs to be reseted, but dont do it by your self, look for help.

Regards,

Some freezers don't operate with coils. If you search for that on google you might be able to find the parts manual. Your other option, assuming it is broken, is to find a replacement. http://www.refrigerationice.com/Services.html

It is a defrost problem. Either the defrost timer is not working or the defrost heater is shorted out. You will need to ohm out the heater. It should have close to infinite ohms. If "open" then that is your problem.

Sorry to read about your problem. you can have many different problems.
I think you have lost freon, but you could have the problems below.

1. Bad temp control
2. Defective compressor
3. Defective start cap
4. Defective overload protector
5. Defective control board

I suggest you call a service company.

Good day,
When running, the low side is usually about 2 to 4 lbs pressure. The high side is determined by the load and the temperature in the room or area. Minimum 125 lbs. maximum approx. 150 lbs.

Good Luck and please rate 4 thumbs up for the free answer

There is a starter relay on the compressor. It sounds like it needs replacing. If you listen for awhile when it trys to start the compressor there will be a clicking sound but then nothing will happen. That is the most likely cause.
