Question about Heating & Cooling
If the boiler has a 24 volt thermostat system, it may not be the thermostat that has failed. It may be the 24 volt inline transformer that's failed. To find out, you will need a circuit tester to make sure power is getting from the transformer to the thermostat. This way, you will know what needs to be replaced.
