I bought my house with an electric furnace, brand is Nortron. The following is the exact situation:
- Thermostat is set to 18 Celsius.
- Air temp (from thermostat) is 21 Celsius. So furnace should not be running.
- Thermostat is only set to heat mode. So no AC.
- The duct above the heater is hot. Way above the duct, it is saying 40 Celsius.
- No Fan of course as current temp is greater than thermostat.
Clamping an amp meter on the furnace breaker is registering 40 AMPS.
After fiddling with the switches (there are 3 switches), didn't really change the settings, just flip, then flip to original/default position, amps is now 6.
What is scary is I got an electric bill that is 200 dollars more than what I'm used to, so this has been happening for more than a month. Since it was summer last month, 100% sure thermostat didn't trigger. Just that it is generating this heat for no reason at all...
What could be causing this? I'll gladly provide more context if needed. For now, I turned off the breaker to avoid burning more money.
