IF THE FAN WILL NOT TURN ON FROM THE THERMO-
STAT:
If there is no high voltage to the PCB:
1. Check the plug/receptacle connection; this brings power to the
PCB. Make sure the plug is connected properly.
2. Check sequencer number 1 and the plug’s wiring; the yellow
wire should be connected to pin number 9 of the plug and the
limit switch. A black wire should be connected to pin number
7 of the plug and to sequencer number 1.
