Why is my Emerson thermostat not cooling?

There could be a few possible reasons your Emerson thermostat may not be cooling. See the possible causes and the fixes in the table below

Loose thermostat wiringEnsure wires are securely attached to the system and thermostat.

Incorrect thermostat setting

Check if your system is set to cooling and the temperature is set to a point lower than the room temperature. If the temperature is higher than ambient, the thermostat will not call for cooling.

There may be up to a five minute delay before the thermostat calls for Cooling if the compressor lock-out option is selected in the configuration menu.

So it’s always best to wait for at least 5 minutes after you turn on the cooling.

Lose wiring

Check the wiring behind the thermostat display and ensure that wires are securely connected and attached.
