Troubleshooting Common Tempstar Furnace Error Codes

When you have a piece of equipment like a furnace that is so important to keeping your home comfortable, it’s natural to worry when something goes wrong. There are multiple codes that a modern furnace can throw up, and while none of them are ideal, you will be able to diagnose the issue and get things running smoothly again in no time. It’s easy to become confused when dealing with error codes. They are made up of letters and numbers that can seem completely random at first glance. However, most manufacturers follow standard practices for their error codes; by referring to an error code reference document, you should be able to determine the issue and take appropriate action. If your Tempstar furnace is throwing up an error code as part of its self-diagnostics, there could be one of several reasons why this has happened. In this blog post, we explore some of the most common reasons why your tempstar furnace may give you an error code – and how you can fix it!

Error Code 1: Blower Doesn’t Turn On

If your furnace is powering up as usual but the blower doesn’t start, you have an issue with the blower motor. This is the part of your furnace that pushes air through the ductwork in your home to warm up the air. If it is not running, your furnace will not be able to circulate air throughout the house. The most likely cause for this type of error is a bad blower motor. You may also be able to rule out the blower motor if the furnace cycles on and off without the blower operating. This could indicate a problem with the thermostat.

Error Code 2: Furnace Shuts Off Repeatedly

If your furnace cycles off and on repeatedly without reaching the desired temperature, this indicates a problem with the thermostat. If the furnace is shutting down before it reaches the set temperature, it could indicate a problem with the pressure switch. If the furnace cycles off at the correct temperature and then shuts down again, you may have a problem with the thermocouple or the flame sensor. If the furnace is shutting down before the thermostat has had a chance to kick in and turn it back on, you may have a problem with the control board.

Error Code 3: Furnace Doesn’t Stay Running

If your furnace shuts off before you have had a chance to set the temperature, the furnace may be trying to protect itself from overheating. This can happen if the airflow inside the furnace becomes restricted or clogged. If your furnace shuts off and doesn’t start back up again, the problem could be caused by a faulty pressure switch. If your furnace shuts off and stays shut off, the problem could be a faulty thermocouple or a broken flame sensor.

Error Code 4: Furnace Won’t Start

If your furnace doesn’t kick on at all, the problem could be with the control board. If your furnace cycles on and off without generating any heat, there may be a problem with the pressure switch. If you hear a clicking sound from inside the furnace and it doesn’t power up, you may have a problem with the thermostat.

Error Code 5: Low Voltage Detection

If your furnace throws the low voltage error code, it is probably due to an issue with the voltage. You will need to check the voltage of the circuit that your furnace is plugged into and make sure that it is above 90 volts. If it is below 90 volts, you will need to contact your local utility company to get the issue fixed.

Error Code 6: No Response From The Thermostat

If your furnace cycles on and off repeatedly but the temperature at which it cycles off and on is inappropriate, the problem could be with the thermostat. If the furnace cycles off without kicking back on again, the problem could be with the control board.

What to Do When You Get a Tempstar Furnace Error Code

Check the circuit breaker for your furnace. If it has been tripped, reset it and see if that solves the issue. If not, you will need to start troubleshooting the issue further. Open up the furnace and see if there are any obstructions. If there are, try to remove them. Next, check the thermostat and make sure that it is set to the right temperature. If you have checked all of these things and you’re still not able to figure out what’s wrong, call a professional.

Bonus Tips For When Your Tempstar Furnace is Giving an Error Code!

– If your furnace is kicking off repeatedly, check the circuit breaker to make sure that it is working correctly. If it is, you may have a bad thermostat. – If your furnace is running but not heating properly, check the airflow by opening up the furnace. Make sure that there is no debris clogging up the system. – If your furnace is making a clicking sound but not powering up, you may have a problem with the thermostat. – If your furnace has a low voltage error code, you will need to check the voltage of the circuit it is plugged into. – If your furnace has an error code and none of the above solutions have worked, you will need to call a professional.

Wrapping up

If you are experiencing issues with your furnace, it is important to troubleshoot the issue as quickly as possible. When your furnace isn’t working properly, it can be extremely inconvenient. Not only is it uncomfortable to be in a warm house, but it’s also costly. If you can diagnose the issue with your furnace before calling a professional, you will be able to get it fixed in no time.
