If your Mr. Heater is giving you trouble, it can be frustrating. But don’t worry, there are a few common reasons why your heater might not be working, and most of them are easy to fix. In this blog post, we’ll go through the most common issues and provide step-by-step instructions on how to troubleshoot them.
Check the Power Source
The first thing you should do when your Mr. Heater is not working is to check the power source. Make sure that the heater is plugged into a working outlet and that the power switch is turned on. If the heater is still not working, try plugging it into a different outlet.
Check the Fuel Level
If the power source is not the issue, the next thing you should check is the fuel level. Make sure that the heater has enough fuel to operate. If the fuel level is low, fill up the tank and try again.
Check the Igniter
The igniter is responsible for starting the flame in the heater. If the igniter is not working, the heater will not be able to start. To check the igniter, remove the front panel of the heater and locate the igniter. The igniter should be glowing when the heater is turned on. If the igniter is not glowing, it may need to be replaced.
Check the Flame Sensor
The flame sensor is responsible for detecting the flame in the heater. If the flame sensor is not working, the heater will not be able to stay lit. To check the flame sensor, remove the front panel of the heater and locate the flame sensor. The flame sensor should be clean and free of debris. If the flame sensor is dirty, clean it with a soft cloth.
Check the Thermostat
The thermostat is responsible for controlling the temperature of the heater. If the thermostat is not working, the heater may not be able to reach the desired temperature. To check the thermostat, turn the thermostat knob to the highest setting. If the heater does not start, the thermostat may need to be replaced.
Check the Air Filter
The air filter is responsible for filtering the air that is drawn into the heater. If the air filter is clogged, the heater may not be able to draw in enough air to operate properly. To check the air filter, remove the front panel of the heater and locate the air filter. The air filter should be clean and free of debris. If the air filter is dirty, clean it with a soft cloth.
Check the Exhaust System
The exhaust system is responsible for venting the exhaust gases from the heater. If the exhaust system is clogged, the heater may not be able to operate properly. To check the exhaust system, remove the front panel of the heater and locate the exhaust pipe. The exhaust pipe should be clean and free of debris. If the exhaust pipe is dirty, clean it with a soft cloth.
Final Thoughts: Troubleshooting Your Mr. Heater
If you have checked all of the above items and your Mr. Heater is still not working, there may be a more serious problem with the heater. In this case, you should contact a qualified technician to have the heater repaired.
