Coleman Mach Heater Not Working

If your Coleman Mach heater is not working, you will need to do some troubleshooting. First, make sure the power source is connected properly and the thermostat is set correctly. If it’s still not working, check for tripped breakers or blown fuses in your RV electrical system.

Next, look at the burner assembly and verify there are no blockages that could be preventing proper combustion. Also inspect any wiring going to the control board for signs of damage or corrosion, as this may be causing an issue with electrical connection between components. Finally, if none of these steps resolve the problem you may want to contact a professional service technician or replace faulty parts like fan motors or heat exchangers yourself depending on your level of expertise.

If you own a Coleman Mach heater and it’s not working, there may be several reasons why. First, check to make sure that the power source is active and that all connections are secure. If the power is on but still nothing happens, then it could be an issue with the thermostat or other components in the system.

It’s important to have your heater serviced by a qualified technician if any of these issues arise since attempting repairs yourself can lead to further damage and costly repairs down the road.
