How to Fix Kelevinator Furnace Error Codes

‍

Keeping your home comfortable and energy-efficient in the winter can be tricky. Furnaces in older homes are usually not as energy-efficient as modern furnaces. These older furnaces have indicators to tell you when they need maintenance or repair. If you see a Kelvinator error code on your furnace, you must take action to fix it right away to prevent damage to the unit. The Kelvinator is a device that measures the amount of heat that comes out of an exhaust pipe. It is an output sensor used with other sensors to monitor and control combustion processes in gas-fired furnaces. It is also known as a gas volume measurement system, which calculates the volume of gas being produced by the furnace. This article covers five common Kelevinator Error Codes and what you can do about them.

Error Code 51: Burner Orifice too Small

This error code means that the orifice (opening) at the end of the burner gas path is too small for the amount of gas flowing through it. This will cause the gas pressure to increase, damaging the burner. The problem could be the wrong burner orifice size, a clogged gas path, or a dirty air filter that isn’t getting enough airflow through the furnace. The best way to fix this problem is to replace the incorrect orifice with the correct size. You can find the correct orifice size in your furnace manufacturer’s manual. If the gas path is clogged, you might need to clean it with a wire brush. If you think the problem is due to a dirty air filter, you can try replacing it with a clean one.

Error Code 52: Burner Orifice too Large

This error code means that the orifice (opening) at the end of the burner gas path is too large for the amount of gas flowing through it. This will cause the gas pressure to decrease, which could cause the flame to go out. The problem could be the wrong burner orifice size, a clogged gas path, or a dirty air filter that isn’t getting enough airflow through the furnace. The best way to fix this problem is to replace the incorrect orifice with the correct size. You can find the correct orifice size in your furnace manufacturer’s manual. If the gas path is clogged, you might need to clean it with a wire brush. If you think the problem is due to a dirty air filter, you can try replacing it with a clean one.

Error Code 55: Sensor Malfunction

This error code indicates a problem with the sensor. Sensor malfunctions are usually caused by a faulty wiring connection or a not properly installed sensor. You must first determine which sensor is malfunctioning by resetting your furnace and watching which error code appears on display to fix this problem. Then, unplug the furnace and check the wiring connections to the sensors. If the wiring is okay, you might need to replace the sensor. If the wiring is okay, you can try to clean the sensor with soap and water to see if that solves the problem.

Error Code 56: Electronic Control Failure

This error code means that the control board inside the furnace has stopped working. If this error code appears, the furnace will turn off, and you must call a furnace repair technician. To prevent this problem, you should have your furnace inspected by a technician at least once a year.

Error Code 59: Unknown Failure

This error code means that the Kelvinator cannot communicate with the furnace control board. It could also indicate a wiring issue between the furnace and the control board. This type of error could be caused by a faulty or loose wiring connection or a faulty control board. You must first determine which sensor is malfunctioning by resetting your furnace and watching which error code appears on display to fix this problem. Then, unplug the furnace and check the wiring connections to the sensors. If the wiring is okay, you might need to replace the control board. If the wiring is okay, you can try to clean the sensors with soap and water to see if that solves the problem.

Conclusion

A furnace with a Kelvinator error code tells you that it needs attention. Once you have identified the error code, you can use the information in this article to troubleshoot the problem. While the Kelvinator is an effective monitoring device, it can be tricky to understand. If you have an error code, you need to take steps to fix it right away to prevent damage to your furnace.
