Help! C° to F°

Possibly a dip switch or jumper on the control board.

On the back of your control box cover there is a schematic.

It shows where all your dip switch or jumper settings are and the function they perform.

Was the old power supply the same voltage as what you are using?

Go through the installation manual and wiring instructions to verify everything.

If you are unsure about anything, call a service technician to make sure that it is done correctly and to make sure that it is safe.

It looks like the smaller board has been replaced.
 
Did the old owners say that everything was working?

Is the voltage the same now as it was for the old owners?

I don't know the correct wiring for this model so I can't confirm that it is correct.

Are you sure that all of the wiring is correct?

How did you know what the wiring should be?
