2002 Rockwood Premier Furnace not working

[jvp0719]

I have been trying to get my furnace to fire up, but to no avail.

I have a suburban furnace. I follow the directions exactly... Fan comes on but no heat. Yes, propane is on and working. Fridge gets cold on Propane. Thermostat was tested and works. On switch inside furnace cover is 'On.' What am I missing?

I don't smell propane.
There does not seem to be a propane on/off valve.

Any help would be appreciated.

Thanks

Do you have a strong air flow?

If is seems anemic, you may have a fan too slow to close a safety switch that allows the gas valve to open.

Causes of slow fan speed:

1) Low battery
2) Dirt or bug nest in fan cage
3) motor bearings rusted/failing

If air is robust:

Check for strong flame when all burners on stove lit at same time on HIGH.
Low propane pressure can cause failures to light.

Check for debris in flue. Bug nests in flue can cause an over rich mixture and failures to light.

Here is the trouble shooting manual and wiring diagram.
