Troubleshooting (continued)
No Cool
Possible Cause
System switch not set to COOL.
Outdoor unit disconnect or breaker tripped.
Cooling system requires service or thermostat requires
replacement.
Multi-stage Air Conditioner or Heat Pump:
Second, Third or Fourth Stage Won't Come On
Possible Cause
Your thermostat is designed to determine the optimum
time to activate the second stage. Simply raising the
temperature in heating or lowering it in cooling will not
always force the thermostat to bring the second stage on
quickly. There is a time delay of zero to 30 minutes
depending on the performance of the first stage of the
system.

lower the temperature setpoint below room temperature.
Verify the outdoor unit disconnect or breaker has not been
tripped.
To diagnose this condition:
Press SYSTEM button to select COOL and press
lower the temperature setpoint below room temperature.
Within a few seconds the thermostat should make a soft
click sound. This sound usually indicates the thermostat is
operating properly. If the thermostat does not click after
being reset, contact your installing contractor for a
replacement thermostat. If the thermostat clicks, contact
the furnace manufacturer or HVAC contractor for a service
visit to verify the cooling is operating correctly.
