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:

1. 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.
2. 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.
3. 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.
4. 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.

If it is a propane or gas furnace you need a gas registered technician to diagnose and fix. The likely problem is in the control board.

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

It is gas appliance, it can only be repaired by a certified gas engineer. And worse, it is in a mobile home!https://www.google.com/search?q=coleman+presidential+2+furnace+replacement+parts..

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.
