No Frost on evaporator coils
Compressor, condenser, and evaporator fan are all running. Defrost heater seems to work fine but I can't get any frost on my coils? It forms on the tubing on the left side and bottom of the coils -Thats it!
In the picture I have circled in red the only frosted parts of the coil assembly.
What is the problem?
The picture link you posted does not work.
The model number you posted is incomplete.
If the evaporator is covered partially, possible there is a problem with the sealed system.
The attachment feature doesn't work...
If you want to see a picture I can send it.
I read somewhere that someone had a similar problem and it ended up being the evaporator fan motor. I guess the RPMs were low. They replaced the motor and circuit board and that took care of it. Is there any way of testing the evaporator fan? Or is there a way of verifying that there is a problem with the sealed system?
If there is a problem with the evaporator fan, the evaporator will be completely frozen up.
If there is only a chunk of ice somewhere on the coils, very likely the system is low on Freon due to a leak.
