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.
Coleman Evcon mg9s060b12mp11a fan speed blower slowest setup?
who ever designed and installed your system probably using wrong sizing for duct work and never balanced the air flow-- also should be able to adjust but keep in mind system design need certain air flow over coils so will probably need to redesign the plenum --trunk --and vents
My light is blinking 4 times it will kick off and on then it stops kicking on and i cant find my model number online so i cant do the repairs
The blinking light on your Coleman Mobile Modular Home Electric Furnace can indicate a variety of issues, and it's important to identify the specific pattern of blinking to determine the cause of the problem. In general, a four-blink pattern can indicate that the furnace has detected a malfunction in the limit switch circuit.
The limit switch is a safety device that is designed to shut off the furnace if the temperature inside the furnace becomes too high. If the limit switch is not functioning properly, it can cause the furnace to shut off unexpectedly and display the four-blink error code.
To troubleshoot this issue, you will need to check the limit switch and any associated wiring for damage or loose connections. You may also want to check the furnace filter and make sure it is clean, as a dirty filter can cause the furnace to overheat and trigger the limit switch.
If you are unable to find your model number online, you may be able to find it on the furnace itself, or you may need to consult the owner's manual for more information. It's important to follow the manufacturer's instructions when performing any repairs to your furnace, as improper repairs can potentially cause further damage or create safety hazards.
If you are unsure how to troubleshoot the issue or are uncomfortable working with electrical components, it is recommended that you contact a qualified HVAC technician for assistance.
Coleman Presidential II Furnace: No heat and blower motor is running constantly.
This could be due to either an open safety switch such as a rollout or high limit, or the relay could be welded inside the control board constantly sending 120 volts to the blower motor. A less common cause could be a bad thermostat which can be verified by removing the face plate. If the blower stops, then the thermostat will need to be replaced.
