Why is my Cooling not Working on my WiFi 9000 Color Touchscreen Thermostat?

Last updated

Share:

Your primary cooling (1st stage) is controlled by the Y terminal on your thermostat. (Or the Y and O/B terminal if you have a heat pump system) In addition, the G terminal is activated to turn on the fan in your home to circulate the cooler air.

  • Confirm the furnace / air handler door is closed and turned on. Check the circuit breaker to your equipment.
  • Confirm the thermostat is set to Cool mode and the setpoint (the smaller number at the top of the thermostat display), is set to a temperature lower than the display temp (the larger number in the center of the display).
  • Confirm the message "Cool On" is solid ("Waiting for Equipment" is not displayed ) on the thermostat display.
  • Confirm your wiring is correct, and the wires have good contact in the terminals (tug gently on the wires)

Advanced steps:

Using a multimeter, measure the AC voltage between your Rc wire and your Y wire. Your thermostat operates between 20-30VAC, any reading outside this range should be addressed by a Professional Contractor.
