69 AS Soveriegn AC Issues

I have the original AC still installed my AS, When I bought the PO said it had an electrcial issue. I have replaced everything but fan and compressor. It works great for a little while then it stops cooling. When I replaced all of the electronic gadgetry ( relays, capacitors, transformer) it now seems like that box is getting really hot. Should I put in a couple of small computer fans to draw out some of the heat from inside that enclosed box? Or could it be the thermo switch on the compressor?
Any help is greatly appreciated.

It almost sounds like you are not plugged into an adequate service. I would check to make sure that you are plugged into an actual 30 amp circuit and do not use a "heavy duty extension cord". The heavy duty only refers to being able to drive over it with less chance of damaging it. If the ac is not getting sufficient voltage it will heat up and could damage the compressor unit itself. As voltage drops, amperage increases and thiat creates heat. I tried to run my ac after replacing the fan motor and some other things through just a heavy duty extension cord and a 20 amp outlet and the compressor would only come on for short bursts and then quit. I then wired in a 30 amp outlet from my main panel in my house and used a direct bury 8 guage cord to run out to the trailer and plugged in to that. My compressor works effortlessly now and the ac just runs and runs. If you have a volt meter, turn the ac on and measure the voltage at one of your outlets and see if your voltage starts to drop. If it drops below 110 volts than I would say it is an issue with the power cord/s or supply. It really shouldn't drop below 115. Good luck. Oh yeah, it could just need a recharge too but I would check voltage first.

I will check out the voltages. I am hooked up to a dedicated 30 amp service, but there are other things running as well, a couple of fans. But I wouldn't think those would have a burden on the voltage, but one never knows.
