I am having a problem with a Nuheat floor mat and thermostat. I have installed these systems several times before with no issues. We installed the six by eight mat, 120 volts and followed all of the procedures and verified ohms before during and after. All was okay. We installed the thermostat and started it up. It went through a check list and indicated all systems go. The thermostat then had a prompt to push the GFCI test button. I pushed the button as instructed and there was a loud pop and spark within the thermostat.
The thermostat continued to light up (was not destroyed). I removed the thermostat and checked for any sign of arcing. There was no smell or burnt or melted wires etc. Now the big problem. I re checked the ohms etc. and now have continuity between the line to neutral as well as line to ground and neutral to ground. It is as if something shorted out in the thermostat and fried the wires on the floor mat.
Could it be the thermostat was missing an internal electronic component? Any ideas about this problem?
