Top 10 Most Common Kenmore Gas Furnace Error Codes And Their Fixes

When it comes to repairing appliances or electronics, you will often see error codes listed in repair guides. These error codes might seem like gibberish, but they actually serve as a guide for the user when trying to troubleshoot their device and figure out what is wrong with it. If you are using an older appliance or piece of technology, such as your gas furnace, even more so you may have some hiccups along the way. Not only can these problems be frustrating to deal with, but they can also be potentially dangerous to your home if not fixed immediately. Luckily, most of these issues are pretty simple to remedy once you know what they likely are. Since many of them have to do with the gas furnace specifically, we’ve compiled a list of the top 10 most common Kenmore gas furnace error codes and how to fix them!

Error Code 21: Faulty Pressure Switch

The first thing to check if you’re experiencing furnace issues is the pressure switch. This is the device that regulates the flow of gas going into your furnace. It ensures that your furnace is only getting the right amount of gas to light, as well as allowing the right amount of gas to flow to the blower fan. This is also the culprit if you’re experiencing a furnace that shuts off prematurely. If the pressure switch isn’t working properly, it may not let enough gas through to light the furnace. Additionally, the switch may be letting too much gas through, causing the furnace to trip off prematurely. The pressure switch can be accessed via a panel near the furnace. Simply remove the panel and you should be able to see the pressure switch. If there is a red indicator light on the switch, you’ll need to replace it.

Error Code 25: – Electronic Thermostat

If you’re experiencing issues with your Kenmore gas furnace, check to make sure the thermostat is working properly. If there is an issue with the thermostat, such as it being tripped, the furnace will turn off despite the temperature setting displayed on the thermostat. It may also not respond to changes in temperature at all. If the thermostat is working properly, the furnace will switch on when it senses the temperature of the space it’s located in dropping. In other words, it’s working as it should. If the furnace is still not working after checking the thermostat, you may need to repair or replace the furnace’s main control board. If the furnace is still kicking on but not turning off, this is a sign of a problem with the thermostat itself. If you notice that your thermostat has warped or is discoloured, it’s time to replace it.

Error Code 32: – Electronic Thermostat

If you’re experiencing issues with your furnace and you notice that the thermostat is reading a temperature above the actual room temperature, you may have a faulty thermostat. If the thermostat isn’t reading the correct temperature, the furnace will delay kicking on until it senses the room temperature is low enough. In some cases, the furnace may not turn on at all if the thermostat is reading a temperature above the actual room temperature. If you’re experiencing issues with your furnace and the thermostat is reading a temperature above the actual room temperature, the thermostat may be faulty. If the thermostat is discoloured or warped, it’s time to replace it.

Error Code 35: Shorted Electronic Control Valve

The electronic control valve is responsible for turning the gas on and off in the furnace. It also regulates the amount of gas going to the furnace. If the control valve is faulty, it may be letting too much or too little gas through to the furnace, causing the furnace to trip off prematurely or not light at all. If the control valve is letting too much gas through, it may cause a gas leak. If this occurs, shut off all of the gas to the furnace and call the gas company to come out and repair the leak. If the control valve is letting too little gas through, it will cause the furnace to trip off prematurely. In some cases, the furnace may not light at all. If the valve is faulty, it may need to be replaced or cleaned.

Error Code 38: Electronic Control Valve Failure

While this error code is pretty similar to the one above, it occurs when the furnace tries to light but the control valve fails to open and let gas through. This can be a sign of a serious problem and should be checked out by a professional as soon as possible. If the gas valve is faulty, it may need to be replaced or cleaned.

Conclusion

When it comes to furnace issues, it’s important to try and diagnose the problem as early as possible. If the furnace has shut off, you should turn it off at the source and make sure the pilot light isn’t out before you try to turn it back on. If the furnace isn’t coming on at all, you should check the temperature controls to make sure they’re set appropriately. If you’re experiencing issues with your furnace, but you’re not sure what the problem is, you can use this list as a guide for troubleshooting the issue.
