Tempstar Furnace Troubleshooting

Tempstar Furnace Troubleshooting. A furnace is essential for the survival of you and your family during winter.

In periods before the introduction of central heating, people used to huddle around wood fires to keep warm and lived in freezing conditions.

Furnaces are very important for our day-to-day life because we always want to be comfortable inside our homes, without such thing as a good heating system it would be impossible.

Furnaces have been indispensable since the beginning of time but they do need some maintenance or at least special attention that can cause some malfunctions.

The simple task of troubleshooting them first will prevent you from doing something that could cost you a lot less than calling an expert technician.

To troubleshoot Tempstar furnace problems, we discuss some issues here.

Tempstar Furnace Blower Runs Continuously

A wall thermostat has electrical contacts that control the power supply to the furnace.

If the contact that controls the blower motor sticks closed, it will send continuous voltage to the blower motor, causing the motor to run continuously.

To determine if the thermostat is defective, use a multi-meter to test its continuity. If there are no continuity between (R) and (G) terminals when the thermostat is in the off position, then the thermostat has failed and must be replaced.

The control board, or power supply, of the plasma cutter has relays. The relays regulate the voltage going to each component in the furnace such as the blower motor.

If any of the relays are closed and stuck in place, it will result in a continuous flow of electricity through those components that could damage them over time.

If there is an issue with the power supply unit please let us know and we can either purchase a new one for you or fix your existing one inexpensively.

Tempstar Furnace Blower Will Not Run

If the capacitor is broken or faulty, the fan motor might run slowly. If so, check to see if the capacitor is bulging out of its case or if there are any leaks.

This can indicate that the capacitor has started to break down. If this is the case, consider replacing it. The capacitor can be tested with a circuit tester to make sure it’s working properly.

Blower motors blow through return vents, past heat exchangers, and into the venting system of homes.

Check whether power is getting to your blower motor first, as some wires may have come loose. Your blower fan may be damaged if it does not work properly even when it is turned on. It will need to be replaced in this case.

If the blower fan spins freely but doesn’t work while connected to electrical wiring then make sure that something has not become obstructed within it which would cause it to slow down and stop working altogether.

The best thing to do in this situation would be to simply replace your defective appliance.

Tempstar Furnace Begins To Run, Then Stops

The pressure switch will close when the burner has sufficient airflow. If the pressure switch isn’t working, the ignition process might not ignite, causing stalling and shutting off of the furnace.

To determine if any issues exist with the pressure switch, use a multimeter to test whether or not it is intact.

By testing for continuity, we’ll understand whether or not a necessary piece of equipment is working properly.

If it does not have continuity, replace it immediately if there are issues with this particular part of your furnace then you’re putting yourself and your family at risk.

The flame sensor monitors for a specific level of heat that indicates to it that there is a suitable flame present.

If the furnace is not able to burn whatever it’s meant to, the control board will cut off electricity to the gas valve.

Sometimes, if a flame sensor is dirty or full of dust, it may not detect a sufficient heat output and will send false readings to the control board which prevents its ability to work as intended.

To fix this issue simply grab a fine abrasive pad and clean off your flame sensor so that it can prepare coolant for your furnace again.

If at this point you’re still having problems with your device then one must assume that either the thermostat itself is faulty or your furnace has malfunctioned meaning you have no other choice but to replace both devices entirely.

Tempstar Furnace Has A Loud Noise

The blower motor’s bearings will eventually be worn out and become noisy over time. If your furnace motor is able to be oiled, you might try lubricating it first to see if that will fix the problem.

By lubricating the motor you may be able to fix your problem. You should replace the motor if lubricating the motor doesn’t work or if your furnace motor cannot be oiled.

The draft inducer provides the necessary airflow to your system – and it’s critical for the longevity of that hardworking piece of machinery.

We suggest you inspect the ol’ draft inducer blower wheel as it might have a damaged area or missing fins that should be taken care of,

otherwise, faulty air circulation will result in inefficient heat distribution, which is never good news when barbecuing.
