Typically, you'll find it inside the air handler, either next to or above your furnace. In most newer systems, the button is often directly next to the blower motor, while in older systems, it may be harder to spot as it is sometimes underneath or behind the motor.
In most newer systems, the reset button is conveniently located near the blower motor, which makes it easy to spot and use when needed. In older systems, however, it may be more challenging to locate the reset button on your furnace, as it can sometimes be found underneath or behind the blower motor.
HiCustomerbr />You should not hit your reset button again. Everytime you hit the reset button and the burner doesn't ignite you are pumping oil into the combustion chamber. This can be very hazardous when the burner finally does fire up.
First of all, be aware that not all furnaces have a reset button; however, most do. If your electric furnace has one, it's most likely located within the blower housing, next to the motor. If you own a gas furnace, it's probably located within the control panel. Check your owner's manual for specifics.
There are several reasons why your furnace may not turn on. The most common include a broken thermostat, gas line issues, clogged air filters, blocked ductwork, a tripped circuit breaker, and issues with the furnace itself.
Leave the breaker(s) off for at least 10 minutes while the system is off and “rebooting.” After 10 minutes have elapsed, go back to the breaker box and flip the HVAC breaker(s) back on.
If the flame sensor fails, your furnace may not be able to start or may shut down shortly after starting. Common causes of flame sensor failure include corrosion, dirt buildup, or a broken wire. The gas valve controls the flow of gas to the furnace. If the gas valve fails, your furnace won't be able to produce heat.
Steps to Reset Your Furnace
If you can't find a switch at the furnace you can turn off the circuit breaker to the furnace at the main circuit breaker box. Wait about 10 seconds. Turn the switch or breaker back on and check the furnace to see that it has power again.
You should not reset the burner more than two or three times, the reason is you may be pumping some fuel into the heat exchanger that is not igniting.
If nothing's happening when you're expecting the whir of a blower, check the circuit breaker and fuse. At your electrical panel, make sure all switches related to the HVAC system are on. Reset any tripped breakers and replace all blown fuses, and your furnace should kick back on.
If your gas furnace initiates the start cycle but doesn't fire up, it's likely because of a faulty, damaged, or dirty ignitor/sensor. This is a very common problem — you can try to clean the sensor and replace the ignitor.
Reset the AC Using the Isolation Switch
You can find it on the wall beside the unit or at the condenser. The isolation switch looks like an ordinary light switch with a knob. Once you locate it, turn the knob to the off position and leave it for at least 30 minutes up to an hour.
Furnace Overheating
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.
One of the most common furnace problems is a malfunctioning thermostat. A sure sign your thermostat isn't working properly is if your fan is constantly running. This will cause your thermostat battery to run, and cause your furnace to work inefficiently.
Ask twenty professional HVAC contractors the question, “How Much Does A New Furnace Cost?” and you'll probably get the same answer... “It depends.” On average, the cost of a new furnace can range from $2,000 - $14,2001. However, factors like furnace efficiency, type, size, and much more can impact this range.
First, turn off the power supply to the furnace by turning off the breaker in the circuit box. Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor.
If the lights are still illuminated or flashing with the flame sensor wires disconnected, the primary control is defective and should be replaced.
When resetting your furnace, make sure to press the button only once to avoid engaging the safety lock. Reach out to professionals. In most cases, the safest course of action is to contact your go-to HVAC company if your furnace doesn't work after a power outage.
If your furnace doesn't switch on, the circuit breaker could be shut off. Check your circuit breaker panel to make sure all switches for your HVAC system are set to “ON.” Check Your Thermostat: If your furnace doesn't turn on automatically, the thermostat may have lost its programming or reset.
Use the Furnace's Power Switch
Most furnaces have the switch on the exterior of the metal cabinet that contains the blower unit. Push the switch to the off position. Wait for two to three minutes, then turn it on again. If your furnace still won't respond, proceed to the next step.
The furnace switch is the unit's power source and typically located next to the furnace or on its side. It closely resembles a light switch. First, confirm the switch is in the "on" position, and if it is, see if your furnace starts up.
