Common Reasons Your Furnace Brakes Down
The heating system is very important in a home because it not only regulates the temperature in the house but also makes your home comfortable to live in. Therefore, it is very important to maintain, repair or replace your heating system as required.
One of the problems associated with a furnace is tripping of the circuit breaker when the gas or oil fueled furnace is turned on. When it’s broken, you need to hire an expert to repair your heating system to avoid further damage. However, some people tend to reset the circuit breaker and carry on for a period of time until the circuit breaker trips again! This is not going to repair your broken unit because it can lead to serious damages that can make you incur heavy losses by having to replace multiple parts or even the entire HVAC system. A circuit breaker trips to protect the circuit from a large voltage surge which can lead to HVAC equipment overload. This means that there is safety issue and you need to call in an professional repair technician or fix it yourself.
A lot of people who own gas furnaces get confused about tripping circuit breakers because they think that gas furnaces do not need electricity. This is a misunderstanding because even if these furnaces rely on gas to produce heat, they still rely on electricity to power other components e.g. the ignition system and the electric blower motor. If you have limited knowledge about gas furnaces, you are advised to hire an HVACR technician to fix or diagnose what is causing safety circuit breaker to shut down the gas furnace unit.
Why would the circuit breaker trip?
Clogged furnace filter – when the filters have a lot of dust, lint and other debris, it becomes clogged making it ineffective. The filter makes the blower motor to strain thus overloading fan electrical parts and tripping the circuit. You can prevent this from happening by cleaning and replacing clogged air filters regularly.
Leaking or dirty air ducts – when your furnace has leaking air ducts, the air pressure lowers in the ductwork making the blower motor fan to overload thus counteract indoor air pressure deficiency. As a result, the blower fan uses a lot of energy (electricity) causing the circuit breaker to trip. You can hire a professional EMCO Tech Heating & Cooling service technician to clean and seal your ducts.
Damaged or broken fan motor – if the insulation of your motor is worn out, it can cause arching in the motor triggering a tripped circuit breaker the heating unit. You just need heating systems expert to repair or replace the motor or look for other reasons affecting the heating system.
