My Carrier Thermostat Is Stuck on Off

Carrier thermostats, such as the Edge programmable thermostat, give you the power to regulate your heating or cooling so that indoor temperatures will be favorable. Problems that can shut down your thermostat include low batteries, circuit breaker problems and dirty or damaged filters. A few troubleshooting steps and guidelines may solve your thermostat's power problems to regain control of your unit's heating and cooling abilities.

Instructions

1. Check the thermostat batteries if your Carrier thermostat is not turning on. A low battery problem is the most common issue that keeps your thermostat off. If the batteries are low, replace them.

2. Check your circuit breakers if your thermostat is still off. The circuit breakers are usually inside an electrical panel next to the the outdoor heat pump. If the circuit breakers are off, turn them on. If the circuit breakers are on, turn them off and then turn them back on. This resets them.

3. Check for a disconnect switch next to your outdoor condensing unit if the thermostat is still not turning on. Make sure the disconnect switch is on. Check the filters on your outdoor unit. If they are dirty, brush off dirt and debris. Dirty filters can cause your unit to shut down.

Tips & Warnings

• Contact a qualified HVAC technician if your thermostat is still not turning on.
