Hi,


Possibly a bad contactor which controls the heating elements and the blower motor.

You can see and order Contactor # 621958 from top right here :

http://www.mobilehomerepair.com/Order4b.html


If you look at the ends, you see a set of two brass colored terminal spades on each side.

With a meter lead on one of the spades on each side, one end should read 240VAC and other end should read 0VAC.

Then, set t-stat to call for heat, test the side silver terminals and should read 24VAC.

IF so, you should now read 240VAC at the end that previously read 0VAC.

IF not, contactor is bad.



Thanks,
Robert

Hi,

Go to the link given to see it, click on pic for enlarged view.

It is the relay switch which energizes the elements and blower motor.


It is on back wall of controls compartment just above the heating element front plates.


Thanks,
Robert
