Suburban SF-30F furnace won't turn on
My Suburban SF-30F furnace won't turn on. It will only click once. Has a Dometic Duo-Therm thermostat. A/C still comes on when moved to A/C but furnace won't come on. Can anybody help?

Don't know what year RV you have so........
Power comes from t-stat to either a stand alone 'time delay relay' OR a 'blower power' (time delay incorporated onto circuit board).
Power then goes to fan motor.......
Fan motor power is from DC Dist Panel FUSE and goes thru a switch/cb on furnace
Check for blown fuse on DC Dist Panel
Check for tripped switch/cb on furnace
If BOTH OK.........blower power module on circuit board bad. New circuit board
