Replace the blower motor
There are several reasons why you may need to replace the blower motor in your furnace. If you notice that your heater is making a strange noise or is overheating, this might be an indication that your machine is bad. However, simply replacing the blower engine will not solve the problem.
You should also make sure that your air ducts are not leaking a major amount of air. One possible cause of a malfunctioning blower motor is a malfunctioning power supply unit. First, remove the front cover of the heater and you should be able to see it. You need to unscrew the two bolts that hold the motor assembly to the housing.
This will allow you to access the motor. You will need a screwdriver to remove the old motor and put the new one in place. Make sure to install the new motor in the appropriate bracket. A blower motor is a vital part of a heater system. Replacing a bad blower motor can restore the system to working order and restore home comfort.
Unfortunately, a new blower motor can cost a few hundred dollars. You can save money by doing the job yourself. Before attempting to replace the blower motor in a heater, you need to shut off the power source first. This is crucial to ensure that you do not risk getting electrocuted by touching the components of the furnace while it is on. If you are not sure whether the blower motor wiring is live, you can use a noncontact circuit tester to make sure.
Check the run capacitor
When doing furnace repairs, you should check the run capacitor to ensure that it is functioning properly. This component is rated at five milliards per second (MFD) and should be replaced if it is damaged. A new capacitor should be installed together with a new motor and new wiring.
When replacing the capacitor, it is important to take note of where all the wiring comes from and to unplug your HVAC unit first. The capacitor is a common component of most heaters and provides a battery-like function for the blower motor. If it is damaged or worn out, the blower motor may not function properly and may even overheat. It may also operate strangely or in short cycles.
Replace the transformer
It is important to replace the transformer in a heater when it is giving you trouble. If you’ve found that your heater’s transformer is faulty, you may want to contact a professional like Big Texas Comfort furnace technicians to replace it. A bad transformer can cause the circuit breakers to trip more often, which can fry your heater’s parts.
To replace the transformer, you will need to first shut off the power and unplug the furnace. You can use a voltmeter to check the voltage in the circuit. It is best to have an expert replace it for you, as they follow strict industry standards.
Check the gas valve
When performing furnace repair, you need to make sure the gas valve is working. You can use an electronic gas sniffer to detect a leak or soap bubbles to test the fittings for tightness. If you detect a leak, you should also adjust the gas valve if necessary. Note that you should check the valve only with the gas turned on.
The gas valve is the heart of any gas-fueled heating system. The malfunction of this component can cause the furnace to stop producing heat. There are several reasons why the valve can fail. These include basement seepage or submersion, a safety circuit glitch, or an electronic gas ignition component.
