Due to the fact that your furnace performs so many different operations, it comes as no surprise that there are a number of fuses involved in its various processes.

Reasons Your Furnace is Blowing Fuses in Canal Winchester, Ohio
A frequent explanation as to why a furnace begins to blow fuses is because wiring has become loose or damaged. A poor wiring connection can easily cause a furnace to short circuit. Faulty wiring can not only cause fuses to blow, but it also creates a serious fire hazard. A professional HVAC technician can inspect your system, check all wiring and connections for any issues, and make any necessary repairs right away.
Problems with Your Thermostat
Some types of thermostats feature metal frames. If the wiring inside these thermostats becomes loose and gets too close to either the metal frame or other wiring, the voltage running through the thermostat can become too high for the wiring to handle. If this happens, the system’s control board will become overloaded and blow. This will result in your furnace’s draft inducer shutting down. The draft inducer is a vital component of your heating system. It eliminates any remnants of the combustible gases produced by your furnace’s heating cycles. If the draft inducer is not working, the entire heating system will automatically shut down for safety.
Water May Be Present in Your Furnace
Water finding its way into a furnace is not uncommon at all. However, the moisture inside your furnace must be eliminated, otherwise serious damage to your heating system can occur. If the situation is not corrected, areas of rust can develop inside your furnace. These rusted areas can turn into holes quickly. This kind of damage can be irreparable. Any amount of moisture inside your heating system can result in short-circuiting and blown fuses. It is a good idea to contact a professional HVAC technician to have your furnace checked for the presence of moisture and have the situation remedied immediately.
Inoperable Gas Valve
If your home has a gas furnace and blowing fuses has become a frequent problem, there may be an issue with the gas valve. The gas valve must be able to open and close freely so that the flow of gas inside your furnace stays regulated. If the valve or one of its components doesn’t work as it should, then it will not be able to do its job, and your furnace will become overheated. This is a situation that creates a serious fire hazard.
The Furnace Needs a New Air Filter
Your furnace’s air filter can become clogged by the pollutants it cleans out of the air that passes through it. If a clean air filter is not present in your furnace, your system will overheat, and the result can be a complete and sometimes permanent shutdown of your HVAC system.
Why Is an Air Filter Important?
Your furnace’s air filter traps the dust, debris, dirt, and other pollutants that would otherwise find their way into your home and circulate on the warm air from your furnace.
A Clogged Air Filter Can Cause Major Problems
Neglecting your furnace’s air filter and allowing it to get clogged will cause your system to become overworked and overheated as it tries to push air through the filter. This can cause your HVAC system to shut down, often permanently.
DIY Air Filter Care
Every 30 days during the time it is in regular use, check your furnace’s air filter. If it is dirty, replace it with a new one. Replace it at least one time during the 3-month cold-weather season.
