I got a 1995 30ft Conquest by Gulf Stearm. The air unit on top is a coleman 13,500btu. The model and serial #'s can't be seen. Where the main power supply connects in the control box shorted out and burnt the pc board. The pc board is a #7330B331. What is the part # for the complete control box assembly I need to be looking for and where would be the best place to get one? You can email me at [email protected]
Try a r/v dealer in your area explain to him what you have and he should have access to the type of unit installed on that particular gulfstream r/v since they are installed as a standard unit at the factory Good Luck \015\012\015\012D ... Air Conditioners

The CMC relay will not energize with the correct power going to it. this is a 230v 3 phase 60hz. system and all the correct power is being aplied. Also my condesor and evaporator fan are working propper and i have also replaced the M13 cab control box. All fuses and relays have been properly checked and are good. Any info and trouble shooting help will be greatly apprieated due to the fact that i am in the 101st air born, US ARMY stationed in Afghanistan.
Hi, Wow, wish you were home!! If the CMC relay has the correct voltage to it, I am assuming 230 volt, 3 phase also, it may be your fault. If its energized on a call for cooling, and does nothing, I would say that this is your faulty componant. I don ... Air Conditioners

Bonaire Integra VSL75 only runs at full speed after a motor replacement. I replaced the motor with the exact same model after the old motor seized and sheared a bearing. No other fault was evident. Now the motor only runs at full speed. I have double checked fan connections and tried reprograming the touch pad fan speed settings with no luck. Can the controllers be faulty after a motor seized and tripped the power box switch? I figured it would just be the motor. Any ideas? Thanks

I changed a light fixture in the washroom and It seems that there was a line in the connection box that also serves the wall air conditioner in the bedroom. After checking all the lamo connections again and all the jumpers in the electrical panel the air conditioner seems to bet out of power. I wonder if there is a internal fuse in the unit or in the fan outside. This is an LG Neo Plasma with remote control.
