4 Causes Of A Blown Fuse In A Heating System

   

The last thing you want during the winter months is for your heating system to malfunction. If the regular operation of a furnace has resulted in several blown fuses, the problem must be resolved immediately.

Although changing a fuse in the system’s panel or resetting the unit’s breaker may provide a temporary fix, the furnace will continue to blow fuses if the underlying problem isn’t addressed. Let’s look at a few causes of the fuse blowing in a furnace.

Unstable Wires

Internal wiring or electrical connections may loosen over time due to the normal vibrations of a furnace or heat pump. A loose or disconnected wire might result in a short that would blow a fuse safeguarding the device. To maintain the wires in your furnace, you’ll need a heating replacement. If you reside in Lancaster, DAC Heating and Air can fix the issue and restore your device to a safe and fully operational state.

An Unreliable Transformer Or A Valve

The transformer changes the voltage needed to power the ignition, timers, and controls. Voltage surges could happen if this component’s efficiency is decreased, making the circuit breaker trip more frequently. Be cautious, as voltage spikes might fry various components of your furnace system.

Check the safety valve on the appliance if you have a gas-powered furnace with a circuit that keeps blowing. The valve may trap too much heat inside the device or force too much air out of it. This frequently leads to the furnace overheating. While installing a new valve on your own is acceptable, it can be quite harmful if done incorrectly.

Dirt And Debris

The blower motor, which distributes hot air through vents, can become clogged with debris, dust, grime, and other impurities over time. If the air filters aren’t regularly replaced, they may gather dirt and debris that eventually finds its way to the blower motor. It will overheat and burn out, which could lead to the high limit failing and breaking.

Fortunately, this shouldn’t be an issue if you’ve been regularly cleaning and servicing your heating system. If not, have it examined and cleaned by our qualified technician for heating installation in Lancaster to ensure your system is functioning properly and to stop further fuse blowing.

 

Water Leak

Although the presence of moisture or water droplets from a humidifier linked to the machine may seem insignificant, this is no excuse for ignoring the problem. Since water leaks can harm your system over time, this issue must be fixed immediately. To ensure there are no leaks, you should hire our technician for heating replacement service in Lancaster to complete this task.

Summary

The fuse in a heating system is intended to safeguard the system from a possible overload or short fuse, so if it blows, several issues may occur. An expert like DAC Heating and Air can fix the issue and restore your device to a safe and fully working state.
