How to Troubleshoot When Your Mr. Heater MH540T Won’t Light

The most likely cause is that the pilot light may not be lit correctly.

Mr Heater Mh540T Won’T Light

The Mr Heater MH540T is a powerful, safe and reliable heating appliance from the well-known Mr Heater brand. It is a propane-powered vent-free model that operates with radiant heat and will provide warmth to up to 600 square feet of indoor space. Unfortunately, there are times when the MH540T fails to ignite as expected. Here is an overview of what could be causing this issue and how you can go about fixing it.

When your MH540T won’t light, you should first check the fuel tank or propane cylinder to ensure it has enough fuel in it. If there is not enough fuel, or if you can hear a faint clicking sound coming from the heater, then it’s likely that the battery in your thermocouple needs to be replaced. The thermocouple is responsible for sensing heat and creating a spark for ignition; if it does not work properly then the heater will not ignite.

Another potential issue could be blocked air vents on the side of the heater unit; ensure that these are free of debris such as leaves and dust so that oxygen can enter and enable proper combustion. This should also be checked if your heater makes strange sounds when attempting to light up such as loud popping noises coming from behind the unit itself.

In some cases a blocked pilot light may also be preventing ignition; since Mr Heater MH540T relies on a millivolt ignition system, you’ll need to know how to reset this in order to start up your unit again. All instructions necessary for resetting your pilot light are available in either your users manual or online at mrheatingproducts.com

Finally, some states may require periodic maintenance that must be performed by an authorized technician; this would also involve replacing any worn out parts such as thermocouple or burner tube gaskets around every two years for proper operation
