I have a PLF754 that is just over a year old. It worked last year, but it won't turn on this fall. It is on a double pole thermostat with another heater that is working and the electric is coming on and off at the heater. Does this heater have a limiter and could it have gone bad? If so, where can I get a replacement?

You need a meter, it will be hard without this! If you have 220v in the wall, then think of it like this; each wire is 120v. Test to each other, you get 220v. The thermostat is a double pole, you said. So think of it like this, its an adjustable temperature controlled switch that lets electricity through at the temp. you set it at. If you have 120v from one wire connected to one end of the element, and the other 120v connected to the other end of the element, then it will work. DO NOT CONNECT THE 120V TOGETHER. IT MUST GO THROUGH THE ELEMENT FIRST. The thermostat should be between the power from the wall and the element, to control the temperature.

Jumpered the bimetal thermostat and everything worked smoothly. Tried to clean contacts in thermostat with no luck, so ordered a replacement. At least it was cheaper than the contactor.
SOURCE: hooking up the thermostat
Thermostats are typically low voltage only no more than 24volts that is supplied from the transformer in your heating unit. you need to look at your low voltage wiring that is in the furnace and write down the terminals that are hooked up. Usually (this is a very typical set up) red wire goes to R which supplies 24 volts. green goes to G powers fan motor, white to W terminal and blue or yellow goes to Y terminal this terminal will usually have another wire in its terminal with it to control an outdoor ac unit likely another red or white wire, and lastly the C terminal has a white wire. That is for a basic heating and cooling system just match how they are hooked up at the main unit to the terminals on your thermostat. the thermostat is just a switch breaking and connecting terminals that allow voltage to carry through it. Shut down your unit while working on it as not to blow the transformer otherwise you are gonna need to replace it to if it isnt fused, that is probably my most common repair from people who have tried to change their own thermostat. Hope this helps
