Oil furnace control
I have a rheem oli furnace with a honeywell R8141 control. It has 3 wires org,blk & white. Blk to limit, org to motor and transformer & white to motor & transformer. Unhooked from the transformer there is 0 volts on orange, 120 on white and 0 on black. 120 coming back to the black from the limit. It seems to me the voltage should be on blk and org, anybody know if this is correct? Also, if I pull the transformer back should the oil motor still run?

Would have to see a schematic of the control to tell.
