Troubleshooting a Rheem Furnace: 4 Common Problems and How to Fix Them

If you’re looking for a furnace that can stand the test of time, then Rheem could be your best bet. These units offer reliable performance and energy efficiency for years to come. However, like any other mechanical device, your Rheem furnace may develop issues from time to time. The good news is that these problems are pretty common and can almost always be fixed right away with some troubleshooting and diagnostic work. So whether you have a red light flashing on your thermostat or need to fix the pilot light on your gas furnace, read on to find out more about common problems with Rheem furnaces and how to troubleshoot and repair them.

How to Fix a Rheem Furnace That Won’t Start

If your Rheem furnace won’t start, there are a few things you can do to troubleshoot the issue. First, check if the breaker panel has flipped off. If so, flip it back on and see if the furnace starts. If not, then you might have a tripped circuit. Next, make sure the gas is on. If the pilot light is out, you need to replace it. If you have a gas furnace, then the burners may be clogged or the gas pressure might be too low. You can clear the clog with a vacuum cleaner and check the pressure with a pressure gauge. If the pressure is too low, get in touch with a professional for pressure adjustment. If the problem persists, then you may want to contact a technician for a thorough inspection of your unit.

Rheem Furnace Won’t Stay On

If your Rheem furnace won’t stay on, then the issue could be related to low voltage to the furnace, tripped circuit, or low gas pressure. To troubleshoot, check if the circuit is on and if there’s power to the furnace. If not, then it may be a tripped circuit or a blown fuse. Next, check if the gas pressure is low. If it is, get it fixed. If the pilot light is out, you may need to replace it. If you’ve checked all these issues and the furnace still won’t stay on, then you may need a thorough inspection by a technician. They’ll go through your furnace and check for any issues. If the problem persists, then you may want to get in touch with a professional for repairs.

Rheem Furnace Pilot Light Won’t Stay Lit

If the Rheem furnace pilot light won’t stay lit, the issue could be related to low gas pressure, clogged burners, or a faulty sensor. To troubleshoot, check if the gas pressure is low. If so, get it fixed. If not, then you may need to clean the burners. Lastly, check the sensor and make sure it’s plugged in and working. If the sensor is faulty, replace it with a new one. If none of these issues are causing the pilot light to go out, then you may need a thorough inspection by a technician.

Rheem Furnace Constant Beeping and Looping

If your Rheem furnace is beeping and cycling on and off, then the issue could be related to an error code or a faulty sensor. To troubleshoot, check the error code. If the problem is related to a sensor, then read the error code and replace the faulty sensor. If the error code isn’t related to a sensor, then you may need to contact a technician for repairs. If the beeping still persists, then you may need a thorough inspection by a technician. They’ll go through your furnace and check for any issues. If the problem persists, then you may want to get in touch with a professional for repairs.

Rheem Condenser Doesn’t Turn On

If the Rheem condenser doesn’t turn on, then the issue could be related to low gas pressure or a clogged filter. To troubleshoot, check the gas pressure to see if it’s low. If so, get it fixed. If not, then the filter may be clogged. Clean it and see if that helps. If the filter is clean, then the problem could be related to low voltage. Check the voltage to the unit. If it’s low, then you need to replace the capacitor. If not, then you may need a thorough inspection by a technician.

Rheem Furnace Other Issues

If none of the issues mentioned above apply to your furnace, then there could be another issue at play. To troubleshoot, go through each component and check it thoroughly. You can also hire a professional to do a thorough inspection of your furnace. If the problem persists, then you may need to replace a component or get in touch with a professional for repairs. While the above issues are common, they won’t always be the cause of your furnace’s problems. If you’ve gone through the troubleshooting tips and you’re still stumped, you may want to call a professional for a thorough inspection. They’ll let you know what’s going on with your furnace and what repairs or replacements you need to make.
