My Suburban propane furnace in my FR 17RBXL will not come on. I pulled the fuse and no red LED indicator light came on. When I pull every other fuse in the panel I get the red LED light indicating break in the circuit. I dismantled the thermostat and bypassed it electrically got nothing. Where would the break in the circuit be?
Do you have a meter?
If so, check the fuse and for power at the fuse. The LEDs are not to be trusted.
Check for power at all points to the furnace.
If no power at the converter connection, bad juju.
Find model number for the furnace and follow the trouble shooting steps.
