On my heat pump, a small 3 amp fuse is located on the side of the quick disconnect plug that connects the transformer + and - wire to the main controller board. You cannot see the fuse unless you pull the plug off the contoller board.
Dirt and dust. Over time, dirt, dust, grime and other contaminants can accumulate and make their way from the air filter into the blower motor, the component responsible for moving heated air through vents. This can cause the motor to overheat and eventually burn out, resulting in the high limit, a built-in safety mechanism that controls the opening and closing of the heater, to malfunction. Moreover, when the high limit becomes caked with soot and debris, the connection will break and the limit will fail
Overheating or a high limit switch that trips often are warning signs that your heating system hasn’t been serviced in a long time. To prevent these situations from occurring, be diligent in maintaining your furnace or heat pump, including all of its electrical components, and schedule a cleaning and tune-up service at least once a year.
