Just purchased and had installed a Enviro M55 cast. Love it so far. I hooked up the el-cheepo thermostat that came with it and all was good. Yesterday the stove shut down due to the high temps in the area, coupled with the temp inside the house. No shock there. This morning the temps dropped as did the temp inside the house.The stove never fired back up on Auto/Off setting. It fires in manual and works great. When I adjust the thermostat nothing happens. No click on the thermostat no firing up of the stove. I disconnected and reconnected the spade connectors on the stove and checked the voltage at the thermostat and I have 5volt. I'm gonna see if it goes into shutdown mode again and then jump the wires on the thermostat to see if it fires the stove. Sound like a bad thermostat to me. Im quite sure people have experienced this before but my searches resulted in nothing. Thanks for the Help. Bill
