Furnace not heating

Transformer, 120 Volt Primary 24 Volt Secondary 40 VA

A furnace transformer is the component that decreases or increases the incoming voltage to power the unit. A faulty transformer can prevent the furnace from heating. If there is no secondary 24 volt power to the thermostat, the furnace trips a circuit breaker when it comes on, or you hear a consistent humming or vibrating noise, it's possible the transformer has failed.

Furnace not turning on

A furnace transformer is the component that decreases or increases the incoming voltage to power the unit. A faulty transformer can prevent the furnace from turning on. If there is no secondary 24 volt power to the thermostat, the furnace trips a circuit breaker when it comes on, or you hear a consistent humming or vibrating noise, it's possible the transformer has failed.

Air handler not heating

A furnace or air handler transformer is the component that decreases or increases the incoming voltage to power the unit. A faulty transformer can prevent the unit from heating. If there is no secondary 24 volt power to the thermostat, the unit trips a circuit breaker when it comes on, or you hear a consistent humming or vibrating noise, it's possible the transformer has failed.

Heat pump not cooling

The control board sends a low voltage signal of 24 volts to the contactor. When the contactor receives the signal from the control board, it closes the circuit, sending voltage to the outside unit components. Some air handlers have a separate transformer for the 24 volt circuit, so if the contactor is not receiving the proper voltage, it's likely this transformer has failed and the component will need to be replaced.

Heat pump not heating

Heat pump won't turn on

Air handler not cooling properly

The furnace control board sends a low voltage signal of 24 volts to the contactor. When the contactor receives the signal from the control board, it closes the circuit, sending voltage to the condensing unit components. Some furnaces have a separate transformer for the 24 volt circuit, so if the contactor is not receiving the proper voltage, it's likely this transformer has failed and the component will need to be replaced.


Furnace wall thermostat not working properly

The unit's control board sends a low voltage signal of 24 volts to the thermostat. When the thermostat's contacts close, a 24 volt signal is sent to the appropriate unit and components. Some furnaces or air handlers may have a separate transformer for the 24 volt circuit. If the transformer has the proper input power but no 24 volt output to the thermostat, the transformer will need to be replaced.

The unit's control board sends a low voltage signal of 24 volts to the thermostat. When the thermostat's contacts close, a 24 volt signal is sent to the appropriate unit and components. Some furnaces or air handlers may have a separate transformer for the 24 volt circuit. If the transformer has the proper input power but no 24 volt output to the thermostat the transformer will need to be replaced. 


Air conditioner wall thermostat not working properly

On some air conditioning units the control board sends a low voltage signal of 24 volts to the thermostat. When the thermostat's contacts close, a 24 volt signal is sent to the appropriate unit and components. Some air conditioners may have a separate transformer for the 24 volt circuit. If the transformer has the proper input power but no 24 volt output to the thermostat, the transformer will need to be replaced.

Some heat pumps may have a separate transformer for the 24 volt circuit. If the transformer has the proper input power but no 24 volt output to the thermostat, the transformer will need to be replaced.
