My fan will not stop running and my pilot will not light on my DAYA-F030N070 Colman furnace.
The inducer draft motor has to run and develop the proper amount of negative pressure (checked with a monometer) to close the pressure switch before anything else happens. Even if the pressure switch closed and the igniter energized, the gas valve wouldn't function until the flame is proven by a flame rod or rectification. The fan continues to run (inducer draft motor) because it is still trying to light. Call a qualified tech before you kill yourself or others
2021 Coleman Mach AC Unit not turning on...
Based on the symptoms you described for your Coleman Mach 10 NDQ Air Conditioner, it appears that there may be an issue with the compressor or the electrical system. Here are a few suggestions for further troubleshooting:
- Check for proper power supply: Ensure that the air conditioner is receiving the correct voltage and that the power source is stable. Fluctuations or insufficient power supply can cause the buzzing sound and cycling of the thermal overload relay. If you're experiencing issues specifically when running on generator power, it's possible that the generator is not providing consistent or adequate power for the air conditioner's operation.
- Inspect compressor and electrical connections: Check the compressor and all electrical connections to ensure they are clean, tight, and free from corrosion. Loose or damaged connections can result in poor electrical flow and contribute to the buzzing sound and cycling of the thermal overload relay.
- Consult a professional technician: Given that you have already replaced the start capacitor, run capacitor, and installed a soft-start kit without resolving the issue, it might be best to consult a professional HVAC technician who specializes in air conditioner repairs. They will have the expertise and tools necessary to diagnose and address the specific problem with your unit.
- Contact Coleman Support: Reach out to Coleman's customer support for guidance and assistance. Provide them with all the details of the issue, including the model number, symptoms, and the steps you have already taken for troubleshooting. They may be able to provide further insights or recommend authorized service centers in your area.
Remember to prioritize safety and always follow proper procedures when working with electrical systems or seeking professional assistance for repairs.
