Hey all,
I have a Stelpro electric furnace, SEF 2021, with a honeywell thermostat.
I have been running into an issue where the thermostat calls for heat, shows "heat on", but the furnace doesn't turn on. The furnace is equipped with manual switch for 'ventillation'. While testing, I just happened to switch the ventillation on for 5 seconds, and then turn it to the off position, and the furnace started working right away and went off at the desired temperature. But the furnace won't turn on when the thermostat calls for heat unless I manually turn on and off the ventilation switch. Any ideas?
