The most common airflow issues are clogged filters, blocked supply registers, and blocked return air vents. Clogged ducts or leaky air ducts can also disrupt airflow and cause the furnace to work harder and run longer, with a tripped breaker as the result.
Call an electrician. They should verify the breaker size, and replace it if necessary. You might just need a new breaker (they wear out if repeatedly tripped).
Overheating of Furnaces also triggers the reset button to trip and shut off your furnace. This event may occur when your furnace is not receiving adequate air flow thus overheating it. Therefore, ensure to check the air filters and the vents to ensure there is proper airflow.
If a new electric heater flew the fuse or a breaker trips, this is the sign of an overloaded circuit. This article will show you how to identify the reason for a tripped breaker, how a GFCI works, and how to reset a breaker. Ensure that the load on a circuit does not exceed the wattage the circuit can power.
If your HVAC system suddenly stops functioning altogether and doesn't respond to user input, it could be due to a blown fuse supplying power to it. If your HVAC system's temperature, fan speed or modes are unresponsive to any adjustments, this could indicate that its fuse has blown.
Overheating is the number one cause of reset button trips. If your furnace is cloistered somewhere where there isn't enough airflow, it may become overheated repeatedly, leading to frequent reset button trips. No Fuel.
It is safe to reset a breaker only if it has been determined that the circuit was overloaded. Repeatedly resetting a breaker could result in an arc flash or a fire. If the cause is due to a short-circuit or a ground fault, a qualified electrician must be notified to investigate the problem.
The thermostat is the most likely culprit here, as an issue in the thermostat will possibly cause the boiler to overheat and trip to switch. The pressure relief valve is another candidate.
Manufacturers often rate MCBs for a certain number of breaking operations, usually between 100 to 1,000 trips under fault conditions. Each trip weakens the internal components, especially the contact points, which deteriorate over time.
Check for overload
Figure out which area of the house the tripped breaker controls, then turn off and unplug everything in that area. Lights, microwaves, computers, everything. Then go turn on the breaker. If the breaker trips immediately, even with nothing plugged in, it's likely you have a short, not an overload.
Can a Breaker Go Bad if it Keeps Tripping? Yes, a breaker can go bad if it keeps tripping. Breakers are designed to protect electrical circuits from overloads and short circuits by automatically shutting off the power when such issues arise.
A damaged heating element, thermostat, or water heater can trip a breaker. Sometimes, electrical circuits can be the source of the tripped breaker.
There are two places you can cut the power to your heating unit: at the breaker box and at its specific power switch. Head to your breaker box and locate the breaker labeled “furnace.” Push the breaker switch to the right to shut off power.
This becomes a legitimate fire hazard if they start overheating from too much current flow. Your breakers will keep tripping as a safeguard until that old wiring gets repaired or replaced.
Signs That It's Time to Replace Your Circuit Breaker
If your breaker seems to be tripping more often than normal, this is a red flag that it can no longer keep up with your home's electrical needs.
If a furnace isn't receiving enough airflow, it may overheat and trigger the reset button to trip. Make sure to clean or replace the air filters and keep the air vents open enough for proper airflow. Occasionally, the flame sensor rod may be coated with dirt and debris, causing the furnace to shut off.
Cause #1: Airflow issues
That can lead to a tripped breaker. The most common airflow issues are clogged filters, blocked supply registers, and blocked return air vents. Clogged ducts or leaky air ducts can also disrupt airflow and cause the furnace to work harder and run longer, with a tripped breaker as the result.
If a fuse keeps blowing, it's almost always thanks to faulty wiring and defective electrical components. Your faulty furnace circuit breaker may also impact your main breaker.
It is typically located in the basement, utility room, garage, or outside your home. The panel will have a door that you can open to access the breakers inside. Once you have located the main electrical panel, look for the breaker labeled as 'Furnace' or 'HVAC.
