Alert Furnace issues

[John Hart]

Anyone have issues with their In-Command system with the furnace not staying lit? Just bought a 2021 Cougar 30RLS and furnace will not stay lighted at any temp setting. Tanks are full.

In lowest cost first.

Low battery voltage.
Control unit.

What does the furnace do? Does it fire up then immediately go out or does it stay lit for a while? If it goes out right away then the spark rod probably needs cleaned and if it runs for a bit then quits you may have a dirty blower or plugged vents and it is over heating.

On another Keystone forum seem people been having issues with the sail switch on the furnace?
