Hi All:
I posted on this about 3 years ago and this year decided to try and fix it again.
The AC works on low speed only (well i assume it's low) if i switch it to high it stops until i put it back on low. The fan only mode does not work at all on high or low speed. I thought a few years ago that it was the thermostat and we replaced it and when tested found it really didn't fix it we decided to let it be, but the last couple long hot road trips peaked my interest in fixing it.
The one speed is cool but come those hot humid days it will be tough to keep up so would like it to work properly.
Here is what I have done:
1. Replaced all three capacitors up on the roof (one at a time with testing in between)
2. Replaced the fan motor
3. Replaced the relay switch just above the capacitors on the roof (i think it's the start relay without going back to my notes?)
4. Replaced the high fan relay inside the RV in the roof assembly
5. Of course i checked all wire connections to be sure they were tight on all the wires I could access easily.
SO we are stumped?!?!?!
Help!
Thanks in advance.

Believe it to be original AC i think 7300 series as the label is worn off on the unit.
