This is a simple system - there is a defrost timer and thermostat, and heater. One of those is out. You can turn the timer with a screwdriver and see if the heater comes on. There is a small hole on the underside of the control housing where the timer hub can be rotated. Turn it till the fridge shuts off; at that point the heater should turn on if the heater and defrost thermostat are good. You can remove the back wall of the freezer to easily tell and make any further checks.
okay turned that and it went off, but can't tell if heater came on
that control housing is in the frig part right.,
I am here to help you solve this; repeating answers just wastes time- if you are unhappy with how I am doing this then I will stop.
I didn't want you to repeat, just confirming what I was doing, as I am not filimar with Appliances, so kinda foriegn to me. I was just checking to see if we did the right thing. Freg went off and we can't hear anything coming on. SOOO would that mean it is the heater, thermostat part? Is that one part or two pcs. Is that what I need to fix problem.
I don't want you to stop, I am just confirming what is being done is right, and you could have answered my question instead of telling me to reread what you already wrote is all.
