Weatherking Furnace Troubleshooting. A furnace is crucial for comfort and survival in the winter. Without it, we would still be huddling around fires to stay warm.
Unfortunately, even with proper maintenance, a furnace will break down or develop problems from time to time because, like any mechanical device or computer, they have a certain amount of wear and tear on them.
If your furnace has stopped working properly make sure to check out these furnace troubleshooting tips to see if you can solve the problem yourself before calling in the pros.
Weatherking Furnace Troubleshooting
We discussed how to troubleshoot some problems of a weathering furnace here.
WeatherKing Furnace Begins Then Stops
The pressure switch only closes when enough air is flowing. If the pressure switch isn’t working, then it might stop closing once there’s enough supply of air.
In such a case, ignition will not start and the furnace will automatically shut down. If the engine doesn’t turn on, check the pressure switch for continuity using your multimeter. If it doesn’t have continuity, replace it with a brand new one.
The draft inducer motor is responsible for pulling air into the furnace’s heat exchanger and removing it from the chimney.
It does this through a powerful fan attached to a shaft. A pressure switch is located at the connection between the casing and chimney and helps to allow the gas ignition which provides heat to our house when we turn on our furnace.
If there isn’t enough airflow in or out of the unit, it can lead to errors with this pressure switch, causing symptoms like your furnace not turning on or shutting down immediately after turning on; all because it hasn’t managed to complete its ignition process, thanks mostly to a faulty draft inducer motor.
WeatherKing Furnace Is Noisy
Over time, the bearings in the bolter motor get worn out, causing the motor to become noisy. If your furnace is only making a little bit of noise, try lubricating it first.
If that doesn’t solve the problem or if your furnace can’t be lubricated in any way, then you just need to replace the motor.
The blower wheel blows air throughout the home and the faulty blower wheel causes the fan to make a lot of noise. Loosen the screws that hold the motor shaft in place because if they are well attached it means that the motor is securely in place.
Inspect if there are any damages on the motor shaft and check if it’s making any sort of rattling sounds whilst it rotates. If you find out that there are damages then you must purchase a new blower wheel.
WeatherKing Furnace Won’t Heat
The wall thermostat is a fancy type of electricity meter. It can also tell us when there may be an issue with our furnace.
If the thermostat does not have electrical continuity then this means that our furnace will stop working and we must replace the old one if we want things to continue as continuously as possible.
The igniter is what lights the gas burner. If the igniter is faulty, problems can arise like the furnace not operating properly.
The first step to troubleshooting this issue would be to test whether or not it works by removing it from its place and inspecting it for cracks. See if any other issues come up after you do this step then make an assumption as to whether or not it is in fact faulty.
WeatherKing Furnace Blower Runs Continuously
The wall thermostat is the device that allows us to control how warm it gets inside our homes and offices.
Sometimes, in order for our indoor temperature to actually match the number of degrees on the thermostat, we need to replace or repair it when it becomes damaged.
To do this you’ll need a Multimeter. First, you’ll test the (R) and (G) terminals on your old thermostat. If they show continuity with each other then your thermostat needs replacing as it’s damaged.
The control board contains relays that regulate the voltage going to different components in the furnace. If any of the relays fail and I will try to explain all of them one by one, it would send continuous voltage through that specific component causing it to malfunction.
For example, if relay number 1 fails while it is closed, it will cause the blower motor to run continuously, which would blow air at high speed out of the furnace – hence the importance of a properly functioning control board.

When the capacitor is defective, the fan motor could be noisy or overheat. To determine that the capacitor is to blame, unscrew it and inspect the condition.
If there are cracks in it or if it looks like the capacitor fluid is leaking out of it, then you should replace this device with a new one. The capacitor can also be checked with a multimeter for signs of failure.
The blower motor blows air through the return vent, past the heat exchanger, and into the ventilation system of the home.
The first step to troubleshooting this issue is to ensure that power is getting to the motor. If power isn’t reaching this area of your ventilation system, you may want to perform a check of your power source.
Otherwise, if your motor has power but isn’t working as expected it might have sustained damage or be out of repair. If your blower motor is not operating properly but is spinning freely then it may be in need of replacement.
