In cold weather seasons, space heaters are commonly the straw that breaks the camel’s back. If your GFCI outlet trips consistently, it could be an electric fault resulting from faulty structural wiring. Its internal temperature-limiting fuse may have blown, or the heater may be dirty. If the thermostat is working and the circuit breaker hasn't tripped, the heater needs servicing. If the problem keeps reoccurring, you may need a new dedicated circuit and outlet that can handle the amperage required by the appliances. CHARLES: But when you plug in the space heater, it shuts down all the power. TOM: … and the space heater is drawing a lot more power than that. Plug the unit into another outlet or install a dedicated 15-amp circuit. https://qlabe.com/heaters/how-to-prevent-a-space-heater-from-blowing-a-fuse 4.

Fuses Are Blown. Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow the fuse.You can use a volt ohmmeter to measure the current draw of the pump and see if it is within factory specified limits. As soon as you request heat the fuse blows and when I try to run the fan to on nothing happens. It occurs when a circuit is attempting to draw a greater electrical load than it is intended to carry.
