Thermostat Lost Its Cooling Option in Morrisville
Morrisville · August 2026 · Jeorell · From our service records
What the customer reported
A Morrisville homeowner called after hours with no AC and thermostat error codes showing communication errors, and the thermostat was not picking up the outside AC unit. After he reset the power at the breakers, the thermostat stopped showing cooling and only offered Off and Heat options.
What we found and did
Jeorell checked both thermostats and reconnected them to the system. Because the zone board had recently been replaced, Jeorell recommended a follow-up visit to make sure the thermostats and board are correct. The visit was handled under warranty.
Result
Jeorell tested operations and confirmed the system was cooling.
