Auxiliary Heat and Emergency Heat are two important features of many heating systems. While their job is to provide additional heat when the primary heating system keeps up, they also cause problems if they aren’t working properly. If your primary heating system is struggling to keep up with the demand for heat in your home, the Aux Heat should kick in automatically. However, if you notice that the Aux Heat isn’t turning on when it’s supposed to, there could be a few different causes.
Check your thermostat settings sure that the temperature is set high enough to trigger the Aux heat function. If it’s too low, your primary heating system may be able to handle the load without any help from the Aux heat.
- Alternatively, there could be an issue with the wiring between your thermostat and HVAC unit. Check to see if any wires are loose or damaged – this could be preventing the signal from being sent to turn on the Aux heat. If you’ve ruled out all other possibilities and still can’t get it to turn on, you may need to call in a professional HVAC technician to take a closer look.
- Emergency Heat is designed to be used as a last resort when your primary heating system has failed completely. However, if you notice that your Emergency Heat is stuck on even though your primary heating system is functioning normally, there could be something wrong.
- One possible cause is a faulty thermostat. If your thermostat isn’t communicating properly with your HVAC unit, it may think that Emergency Heat is necessary even when it’s not. Try replacing the batteries in your thermostat or resetting it before calling in a professional.
- The possibility is that there’s an issue with the wiring between your thermostat and the HVAC unit. Check for any loose or damaged wires this could be causing confusion in the signals being sent between devices.
- Exhausted all other possibilities and still can’t get your Emergency aux heat vs emergency heat to turn off, there may be an issue with the HVAC unit itself. Call in a professional technician who diagnoses and repairs any hardware issues
- Sometimes you might notice that your heating system keeps switching back and forth between modes from primary heating to Auxiliary Heating or Emergency Heating even though temperatures remain steady.
- The most likely cause of this issue is a malfunctioning thermostat sensor. When temperatures fluctuate even slightly around where it’s mounted the sensor sends signals that trigger different modes of operation within seconds instead of minutes or hours as intended for normal operation by design engineers.
