A/C and Furnace

[Andyc-FRF]

I have a 02 Wildcat forester river camper , I took the furnace unit out to have it bench at a local ripped off Shop and they said it was ok .$112.00 for 1/2 hr.
It runs for about 1 second but shuts down , I can hear the igniter and blower running .
The A/C units does the same .
Any ideas or suggestions will greatly appreciated.

Since both the furnace and the air conditioner do the same thing I would say the wall thermostat has gone bad. 02 Wildcats had an analog thermostat and you can buy a new one online for around $35.00.

I agree with oakman, it's likely the t-stat.

Jump the green and white wires together and see if the furnace runs and heats. If it does, then you can just replace it with a new one or you can install a programmable unit such as a Honeywell.

If you want more proof that it's the thermostat, you can jump the Green, Tan & Yellow together and the A/C should run on low.
