Common Issues and Troubleshooting

HVAC control modules are engineered for reliability, but like any sophisticated electronic equipment, they can experience problems that affect the system's performance. Being aware of common issues and knowing how to troubleshoot them can help you quickly restore functionality and minimize discomfort in your home.

Failure to Respond to Thermostat Changes

If your HVAC system does not respond to adjustments made on the thermostat, it could be due to communication issues between the thermostat and the control module. This problem can interfere with the system's ability to maintain desired temperature settings.

• Check for loose or disconnected wires between the thermostat and the control module.
• Reset both the thermostat and control module to clear potential communication glitches.
• Consult a professional if the problem persists, as it may indicate a more complex issue with the system's wiring or electronics.

Inaccurate Temperature Control

Inaccurate temperature control often points to sensor problems or calibration issues within the control module. These issues can cause the HVAC system to heat or cool the home ineffectively, leading to discomfort and increased energy usage.

• Verify that the temperature sensors are not obstructed or located near heat sources.
• Recalibrate the control module to ensure accurate temperature readings and adjustments.
• Replace faulty sensors if recalibration does not resolve the issue.

System Not Starting

A non-starting HVAC system can be due to various electrical issues or faults within the control module itself. This can prevent the system from activating, leaving your home without heating or cooling.

• Check the power supply to the HVAC system and control module for any interruptions.
• Inspect fuses and circuit breakers associated with the HVAC system for faults.
• If electrical components appear in order, consult a technician to examine the control module for internal issues.
