What is the voltage in the Rv when trying to run? You need at least 108 volts when the A/C is operating.

Don;t know if this will help but I have a 83 Holiday Rambler TT with a Coleman TSR A/C unit and I store it 6 months a year. When I retrieve it I need to hand start the fan motor. I have two spots to oil so I remove the shroud, 2 drops of oil and it will run until left dormant.

Is it your dash air that is not working or the roof unit?

"Sometimes a low voltage light comes on"


The voltmeter is your friend, Get a good one and plug it in..

Ideally you need to measure the 120vac being delivered to the A/C. in practice this is not a simple job,, But you can measure it on any non-inverter powered outlet,

Either a good digital multimeter (Which does other thigns) or a Kill-a-watt is fine here.

Home is where I park it!
