Customer Question
I have a 58MCA100-1-16...

I have a 58MCA100-1-16 about 15 years old. The flame roll out switch keeps tripping. It may operate correctly for 1 or 2 days or maybe only an hour. When this happens the blower fan runs continuously until power is shut off to the furnace. All combustion air vents have been inspected, no obstructions.

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

New filter installed recently. Thermostat is set according to how warm we want it in the house.

Contractor's Assistant: Do you plan on doing the work yourself?

Possibly, depends on the problem.

Contractor's Assistant: Anything else we should know to help you best?

Nothing else I can think of. Does the FRS fail over time.

Tripping rollouts are an indication of a clogged heat exchanger. It will need to be cleaned. This sually isn't a DIY project.
