A Guide to Deciphering Ruud Furnace Error Code 45

If your home’s heating system is powered by natural gas, you’ll likely have a Ruud gas furnace in your basement. A Ruud gas furnace is a combustion-type heater that burns natural gas as its primary heat source to heat and cool your house. If you own a Ruud gas furnace, then you will need to be able to identify the error codes produced by the device so that you can troubleshoot the problem quickly and efficiently. A failure of your Ruud gas furnace could lead to an extended power outage in your home or an increase in your energy bills. Fortunately, there are numerous resources available on the Internet for diagnosing and fixing common problems with these devices.

What does Error Code 45 mean?

Error code 45 is a code that is generated by your Ruud gas furnace’s control board when the device detects a problem with the flame sensor. The flame sensor is a part of the device’s safety monitoring system that uses infrared heat to detect when the flame is present in the burner. If the sensor thinks there is no flame present in the burner, then it will signal the control board to shut down the burner. The flame sensor is equipped with a three-second time delay feature that allows the sensor to activate only after it is sure there is a flame in the burner. If you have a Ruud gas furnace with Error Code 45, then it could mean one of two things. First, the sensor could have detected a flame, but the flame was extinguished before the three-second time delay elapsed. Or, the sensor did not detect a flame at all.

The solution to error code 45

To fix error code 45, you need to check the flame sensor to make sure it is clean and not blocked. If the sensor is dirty, you will need to clean it. If the sensor is blocked, you will need to clear the obstruction. You may also need to replace the sensor if it is broken. Finally, you will need to check the flame sensor wires to make sure they are connected properly.

Ruud Furnace Error Codes 42 and 49

Error codes 42 and 49 are the most common code combinations generated by the Ruud gas furnace. The difference between these two code combinations is that error code 42 means the device is not receiving any power, and error code 49 means the device is receiving an excessive amount of current. Ruud gas furnace is powered by a high-voltage circuit with an aluminum wiring. If the wiring is faulty or has been damaged, it can start conducting electricity excessively. In such situations, the wiring inside the furnace blows out due to excess current flow, and the control board stops functioning. If your Ruud gas furnace is generating either error code 42 or 49, then you need to call an expert to fix the wiring inside the furnace. You can also check the circuit breaker to make sure it is not tripped.

Ruud Furnace Error Codes 51 and 52

If your Ruud gas furnace is generating error code 51, it means that the device’s fan motor is not working. And if the device is generating error code 52, it means that the blower fan is not working. The blower fan of the Ruud gas furnace pulls fresh air from the outside of the house to burn the natural gas inside the furnace. And the fan motor pulls air inside the furnace through the combustion chamber so that it can be expelled outside the house. Both the fan motor and the blower fan are equipped with standard replaceable thermal overload protection devices. If the device malfunctions, it trips the thermal overload protection device, which will lead to a false error code.

Ruud Furnace Error Code 53

Error code 53 is generated when the control board detects that the pressure switch inside the furnace is broken. The pressure switch inside the furnace monitors the pressure in the combustion chamber of the furnace. If the pressure inside the combustion chamber is more than 10% above the normal pressure, the pressure switch trips and the control board stops the furnace from functioning. The pressure switch is a common part inside the Ruud gas furnace that malfunctions due to excessive heat or vibrations. If the pressure switch inside your furnace is broken, you will need to replace it.

Ruud Furnrae Error Code 61

If your Ruud gas furnace is generating error code 61, it means that the device’s combustion blower is not working. The combustion blower of a Ruud gas furnace is designed to draw air from the outside and direct it into the device. The blower then pulls the combustion gasses from inside the device and directs it outside. The combustion blower is equipped with a standard replaceable thermal overload protection device. If the device malfunctions, it trips the thermal overload protection device, which will lead to a false error code.

Final Words

At the end of the day, a Ruud gas furnace is an important part of your home’s heating system. And if you want to avoid the trouble of dealing with faulty systems, you need to maintain them regularly. A faulty furnace could shut down your home’s heating system at a time when you need it the most. Therefore, you must be able to identify and fix the error codes generated by your furnace.
