Welcome to FTE. :drinks:

Does your cooling system hold pressure? Have you used a IR thermometer to see what your temps are before and after the thermostat?

Where did you get the new thermostat? I spent two winters chasing no heat only to discover not all thermostats are equal. Finally swapped yet another thermostat but this time OEM. 10 minutes later I had heat again.
