O appears on my control Board. Manual says the L-250 manual reset high temperature switch has tripped.
Remedies - Using the owner's manual, locate the L-250 high temperature switch. There is a red button located on the back of it. Press the red button. My problem, I don't see any red button. Can anyone help, as it is Freezing out and house is getting pretty cold
