Defrost timer might not be working

Hi,
First I would check the fan in the freezer. Listen to see if it is running
It moves air to the ref from the freezer
Then check to see if freezer control is turned WARMER, which makes the Ref. colder
Also this might be a common Defrost problem, Ice
is not being melted by the defrost system.The fan can't blow through the coils into the fridge.
Take out back panel of freezer to check for ice buildup. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

It is a cheap piece of junk. I bought one just this week and the defrost timer gets stuck so it's going back...........

did you read out the heater to make sure it's bad,do you have power coming to the heater

twist your defrost timer with a screwdriver clocwise till it will click and compressor shut off, check voltage on defrost heater. You should have 120volts.When wait 20 min if compressor start up back and defrost heater is off ...your timer is fine. It can come on early then 20 min....
P.S. defrost heater located on the bottom of the coil, also make sure your defrost thermostat is frozen when you going to check voltage on your heater. Thermostat located on the top of your coil.

The solution to all of the above problems. Disconnect the blue wire from the timer and connect a wire from the white neutral to #1 pin on the timer. As shown the timer operates thru the defrost bimetal

If a defrost system is not working you will get, either no cool or frost build up.

Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.

• possible causes:

1. bad defrost timer
2. bad defrost heater (in freezer)
3. bad thermo switch in freezer

If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.

Empty and unplug unit till defrosted.
