| LR44 | LR44 | 1.5V |
Checking the Wiring
7. Utilizing a multimeter to check voltage on the thermostat:
- Flip off the ability to the thermostat on the breaker or fuse field.
- Find the wires behind the thermostat and determine the frequent wire (normally black, white, or blue), the heating wire (normally purple or blue), and the cooling wire (normally inexperienced or yellow).
- Set the multimeter to measure AC voltage.
- Contact the black probe of the multimeter to the frequent wire and the purple probe to the heating wire.
- Examine the show of the multimeter for a voltage studying. A studying of 24 volts or larger signifies that energy is reaching the thermostat.
- Repeat the check by touching the purple probe to the cooling wire. You also needs to get a voltage studying of 24 volts or larger.
- If you don’t get a voltage studying on both wire, there could also be an issue with the wiring or the ability provide to the thermostat.
Wiring Troubleshooting:
| Symptom | Doable Trigger | Resolution |
|---|---|---|
| No voltage on the thermostat | Energy just isn’t reaching the thermostat. | Examine the circuit breaker or fuse for the thermostat. If the breaker or fuse is tripped or blown, reset or change it. |
| Voltage on the thermostat, however not on the furnace or air conditioner. | Damaged wire between the thermostat and the furnace or air conditioner. | Use a voltage tester to test for continuity alongside the wire. If there is no such thing as a continuity, change the wire. |
| Voltage on the thermostat and furnace or air conditioner, however no heating or cooling. | Defective thermostat, furnace, or air conditioner. | Exchange the thermostat or contact an HVAC technician to test the furnace or air conditioner. |
