Orbit Thermostat Troubleshooting

If you are running into any issues while using your Orbit thermostat, then this article has troubleshooting steps for issues we expect to see, and should be able to help.

If your thermostat wires are not labeled and you have no way to find out which wire is which, then we recommend contacting an HVAC Technician to help find out what each of your wires leads to.

If the screen is blank

  • Check Batteries.

    • If batteries are good, then the device may need to be replaced. Please click here to get in contact with our Customer Care Team

  • Make sure wires were properly inserted into the wiring terminal.

    • The copper of separate wires should not be touching.

    • The plastic wire should not extend into the terminal.

  • Check to see if the screen is on & set temperature is visible

    • If the set temperature is not visible but the screen is on, check heat/cool mode switch is in proper heat or cool position.

  • Check if the snowflake or flame icon is solid.

    • If the flame icon is not solid, check set temp is greater than the current temp

    • If the snowflake icon is not solid, check set temp is lower than current temp

  • Check the circuit breaker to the HVAC system and reset if necessary.

  • Make sure the power switch at heating and cooling system is on

  • Make sure the furnace door is closed securely

Fan runs continuously or not at all.

  • If running continuously, let the thermostat sit for 30 min. to allow the temperature to stabilize.

  • If the fan icon is on with no fan, or if the icon is off but the fan is running.

    • Verify that the G wire in the thermostat is connected properly

    • Verify copper wires are not exposed & touching other wires

    • Verify heating/cooling power switch is on.

    • Verify the circuit breaker isn’t tripped.

    • Verify furnace door is closed securely

Incorrect Room Temperature.

  • Let the thermostat sit for 30 minutes to allow the temperature to stabilize

  • Check the placement of thermostat, make sure it’s not in an unusually drafty or heated area

  • Verify the wall hole for the wires is insulated properly.

  • Check temperature offset. *see instructions
