Why Does My Furnace Keep Blowing the Fuse?Posted On: January 11, 2016
When your furnace keeps blowing a fuse, you need to take action quickly. Regularly tripping the fuse can be a fire risk because it indicates an electrical problem. Replacing the fuse or resetting the breaker can temporary fix the problem, but if the underlying issue is not fixed, the fuse will just blow again. To protect your family and ensure your furnace keeps working as it should, you need to find the source of the problem. While there are a number or problems that can lead to this trouble, you need to get to the bottom of the problem quickly to determine if your furnace needs to be replaced.

Blown fuses usually result either from an appliance putting too much strain on the fuse or by an electrical short in the system. Since some furnaces can require a lot of electricity, homeowners must ensure that they have an adequate electrical system to support the furnace. After resetting the circuit breaker and replacing the fuse, if the fuse keeps blowing, there might be an electrical short in the electrical system that supplies the electricity to the furnace. In this case, you should call an electrician.
Sometimes the blown fuse in the furnace comes from a malfunctioning transformer. In this case, your will need a technician to come and replace the old transformer with a new one.
Insufficient Fuse Size
If the fuse in your furnace is too small and cannot handle the wattage, it can cause your fuse to blow. If this is your problem, simply replace the fuse with a larger capacity fuse that can handle the electrical demands.
Malfunctioning Thermostat Wire
If your thermostat wire touches the metal frame of the furnace, this can cause a blown fuse. When a thermostat wire touches the metal frame of the furnace, it can deliver more voltage than the wires are designed to handle. This will blow the fuse on the control board, causing the draft inducer to not start, which then stops the rest of the furnace functions from working properly.
Sometimes, your furnace may seem like it has blown a fuse, but it is actually suffering from loose wire connections. This is usually a good place to start looking for problems with your furnace as loose wires can usually be detected with a voltage meter. If loose wires are detected, they should be repaired or replaced by an electrical or HVAC technician.
