Hello.
I have a customer that has a janitrol model #WH-05-0.
The problem is that the fan runs all the time, whether the burners are on or not.
I think it's the fan limit switch but not sure.
I would appreciate any help.
I work for Homeowners Plumbing/Heating in Howell Michigan.
Also could you please tell me the part number?
Thank you.
Garnett
