Where can i find a thermostat for martin stamping electric wall mount heater model fw430 serial number e 7215?

Answer 1

A King WT-1 (single pole) or WT-2 (double pole) replacement thermostat will work for Martin Industries heaters that do not use a thermocouple (which looks like a length of copper tubing with a bulb on the end).

Check your thermostat. If it does not have a thermocouple, count the number of wires coming from it. If it has two wires, order a WT-1. If it has four, order a WT-2. Both are available online. Make sure there is adequate room to mount the new thermostat. They need about 2 inches length by 1 inch width, and are maybe 3/4" to an inch deep.

In my case, there was plenty of room. Because these thermostats are made for King brand heaters, you will likely have to do small modifications to the mounting plate to mount the new one. I had to drill two small holes for the screws that mount the King version to the plate. I also had to provide two wire nuts for connections. Other than that, installation is straightforward. A wiring diagram is provided with the new unit which - while not totally accurate to the Martin application - will guide you.
