If your Honeywell thermostat is not kicking on the heat, check the batteries first. Make sure the thermostat is set to 'Heat' mode and the temperature setting is higher than the current room temperature. If the issue persists, inspect the circuit breaker and furnace switch to ensure they are on. Lastly, ensure the filters are clean, as blocked filters can prevent the system from functioning properly.
