Why is my auxiliary heat not working?
Another unlikely, but possible, cause of “no heat” on a heat pump system is a failure of the heat pump itself. The reason that this is an unlikely cause is the fact that the auxiliary heaters should energize to keep the space warm even if the heat pump stops working.
Why is my furnace not responding to thermostat?

Why does AUX heat keeps coming on?
Aux heat should only kick on when the heat pump can’t produce enough heat to warm your home on its own. This is typically caused by one of three factors: when it’s below 35° outside, you’re trying to heat your home by 3° or more, or your heat pump is in defrost mode.
Why does my heat pump keep switching to auxiliary heat?
Usually, once outdoor temperatures fall below 35°, a heat pump will struggle to keep your home warm and will automatically switch to AUX heat. And when outdoor temperatures drop too low, there’s simply not enough heat in the outdoor air to keep your home warm.
Can an old thermostat cause a furnace to stop working?

The furnace may be in fine working order, but it cannot keep your house warm without the proper marching orders from your thermostat.
Why does my auxiliary heat come on when my thermostat goes off?

Why won’t my furnace respond to my needs?
Thermostat – If your thermostat isn’t properly functioning, your furnace won’t respond in the correct manner. First and foremost, check to be sure it is set to “heat”. This simple step is often overlooked. Make sure it is securely attached to the wall and no wires appear loose or frayed.
Why is my thermostat not reaching the set temperature?
When you encounter a problem, and your thermostat is not reaching the set temperature, it might be as simple as a dirty or broken sensor on the furnace. In most cases, the flame sensor is more likely to be dirty than broken. Carbon buildup can interfere with the way the furnace reads the temperature.
