The furnace has been idle for a year. Energize the system, single blink. (lockout, to many tries), but happens on initial attempt. Push/release switch behind cover several times and hold in, furnace starts exhaust fan and main blower fan come on, exhaust stops after 10 seconds, main fan continues to blow. When fans come on 5 blinks, open rollout switch code. The unit never got gas, no igniter no glow.

The rollout switch is usually located near the burners. It's a small switch with two wires going to it, and there is a small button between the wires that you can push to reset. Try that and let me know if it works.

Thanks for the quick response. It's a summer house upstate New York. I'll give your suggestion a try and give you a heads up when I go there again. Thanks again!!

Look forward to hearing from you.
