Heat not working?

Finally got it figured out. Loose plug in connection to fan blower under counter! Thanks for all suggestions. Now I know heating system upside down.

Keep any other suggestions coming. Thanks

If the Tstat & furnace has a fan only setting try that - if fan runs then you have power.

If it has air/heat turn to air then back to heat - can stick even when it looks like it is on heat

Have someone turn Tstat on to heat and stand out by the vents - do you hear the pre fan turning on? Do you hear clicking?

If manual Tstat turn up to the highest setting.

Make sure that Aux/house battery switch is on. If interior lights work, it's on.
If off, your furnace, lights, don't get 12 volt DC power.

Any igniters clicking or popping sounds? Do any stove burners light now?

Check 12 volt dc connections at thermostat and furnace including ground wire. Check 12 volt dc fuses and fuse holder connections.

Sounds like the fan motor fuse....

Defective thermostat? In my rig the thermostat has a battery - worth a look.

Stove burners were turned on also.
