I have an overhead gas blower furnace in the garage. I had it serviced last winter when the transformer fried.
Trying to fire it up for the first time this year, and the pilot won't light.
I'm sure that the gas supply valve is open.
I thought maybe I just need to wait for the air to purge after opening the valve, but I held the pilot button down for about 5 minutes, and it still won't light.
Should I hear a hiss or smell gas, or the amount involved in a pilot too small?
