Thermo Pride Control Reset / Low Voltage Recovery Issue

Furnace will not start after a power outage.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blown control board fuse, Power surge damage to Thermo Pride control board, Thermostat lost programming, Tripped GFCI or service switch

Safety First: Turn off power before inspecting the control board.

Check service switch and breaker: Ensure both are ON after the outage.
Inspect board fuse: Replace a blown low-voltage fuse with the same rating. If it blows again, there is a short.
Reset thermostat: Reprogram or reset the thermostat if it lost settings.
Surge damage: If the board shows no signs of life despite proper power, it may have been damaged by a surge and require replacement.
