THERMOSTAT ADJUSTMENT
AIR CONDITIONING ADJUSTMENTS:
ADJUSTING A/C THERMOSTAT:
THE AIR CONDITIONER THERMOSTAT CONTROLS COIL TEMPERATURE. THERMOSTATS ARE SHIPPED ADJUSTED FULLY
COLD (CLOCKWISE), AND IN THE MAJORITY OF CASES, THE A/C WILL OPERATE CORRECTLY AS SHIPPED.
TURNING THE KNOB TO THE RIGHT (CLOCKWISE) MAKES THE SYSTEM OPERATE COLDER. IF THE THERMOSTAT IS SET
TOO COLD THE EVAPORATOR COIL WILL "ICE UP," MEANING THE EVAPORATOR COIL IS RESTRICTED WITH ICE, AND
COLD AIR FLOW WILL BE REDUCED.
TURNING THE KNOB TO THE LEFT (COUNTERCLOCKWISE) MAKES THE SYSTEM OPERATE WARMER. THE COMPRESSOR
CLUTCH WILL CYCLE OFF FREQUENTLY. THE EVAPORATOR COIL WILL NOT GET AS COLD AND THE AIR TEMPERATURE
WILL NOT BE AS COLD.
1.)
SYMPTOM:
THE A/C WORKS WELL AT FIRST THEN QUITS COOLING. THE AIRFLOW FROM THE VENTS IS LOW,
AND THE COMPRESSOR CLUTCH CYCLES INFREQUENTLY.
SOLUTION:
THE THERMOSTAT IS SET TOO COLD, AND THE EVAPORATOR IS "ICING UP" AND RESTRICTING AIRFLOW.
ALLOW THE ICE TO MELT
AND SET THE THERMOSTAT WARMER (COUNTERCLOCKWISE) 1/8 OF A TURN EACH
ADJUSTMENT UNITL THE SYMPTOMS DIMINISH.
2.)
SYMPTOM:
A/C NEVER GETS COLD, AND THE COMPRESSOR CLUTCH CYCLES FREQUENTLY.
SOLUTION:
THE THERMOSTAT IS TOO WARM. SET THE THERMOSTAT COLDER (CLOCKWISE) 1/8 OF A TURN EACH
ADJUSTMENT, UNTIL THE DESIRED AIR TEMPERATURE IS REACHED.
AVOID SETTING THE THERMOSTAT TOO COLD.
