My fridge doesn't get cold as it should.

Hi Quintin, Thank you for your question. Few things we will need to check. First, make sure that when you open your freezer door, that the evap fan motor is running. You should be able to hear it with no problem. If it is not running, but the compressor is, you will need to make sure the fan is getting 120 volts with a multimeter. If it is receiving 120v and not running your fan will have to be replaced. If the fan is running upon opening the freezer door, check to see if the back panel is completely frosted up. If in fact it is, you will be looking at a defrost issue. If the Refrigerator is just sitting idle and does not seem to be running at all, ( no fan, no compressor, no noise really at all) you could be looking at a defrost timer also… Check your fridge for these few symptoms, and please get back to us with anymore information you can provide.
Attached is links to the timer, fan motor, defrost heater and defrost thermostat…. You may also want to remove the back panel by compressor and verify that the compressor fan motor is running.
Thanks, Tony-AceTech52
