Stan.
Thanks. I assume that is for a Winny, but a Workhorse by any other name is still a Workhorse. I think I am a little under 2 lbs. now. I may shoot a little more in and see what happens.
Tom

He recovered 3/4 lb and it has 1.5 lb now. When he put in 2 lb pressures went up and temperature went up also. Compressor seems to cycle fine. Low pressure line at the evaporator is cold but not real cold. Some condensation from the evaporator at times. Low pressure 40-50 and high pressure 275. Heater control valve works OK. I pinched off a heater hose just to be sure. Dash vents seem to change over fine. I am running it on Max-air. We washed out the condenser. Electric cooling fans are running.
Any ideas.
Thanks, Tom
Im having the same prob. I am almost possitive that your water valve that should close,while a/c is running not letting hot water pass through the heater coil.Your a/c will run great but when conditioned air blows through a hot heater coil it gets hot again.Hope this helps i diddent read all replys sorry it someone already suggested.

Hi RRussell
The heater control valve was one of the first things I checked. I pinched off the input hose with a clamp for testing, and it seems to be working OK. They can be problematic though. Easy to test with a clamp or visegrips. Thanks for your input.
Welcome to the site.

Hey Tom, got back from 3 weeks of actually using the RV (gasp). Dash A/C was working fine and then compressor shut off. Quick look under the hood and some wire wiggling and lo-and-behold ... thermostat was intermittently failing. Wedged a little piece of wood between the connectors and worked for rest of trip. Pulled it today and has intermittent high resistance across contacts. Evans calls it a thermostat but it's a fixed range of 31 - 39 degrees so I think it's really a freeze detector. New one on order.

Hey Bruce. Welcome back.
I don't think I have one of those. Good job figuring it out. Glad to have you back on the board.
Tom

Thanks! Mine is about 2 inches away from the resistor pack. Original looks a little different from the replacement. Electrically, its inline with the pressure switch and clutch.

So it turns the compressor off if the evaporator freezes up ? I'll see what mine has to do that.

Yup ... same as the Freeze Sensor in the Dometic/DuoTherm roof A/C. Or, in my case, it shut off the compressor whenever it felt like it ...

It appears to be a capillary tube with what is probably a bi-metal strip contact. Had a quick look inside bu doesn't look like you can clean the contact without damaging the strip ... kinda' cheezy. $40 with shipping but it's another "oh well".

The condenser fan is also in the circuit. I forget the exact order but it's something like:

Battery, ignition switch, A/C switch, pressure switch, thermostat, and then compressor/ condenser fan (parallel).

I'm pretty sure I don't have anything like this. Freezing up is a problem I am not having. The compressor seems to stay on the way it should. Comparing my temps with Bruce, looks like I was expecting too much.

Again, Thanks.
But to save you some typing. I blocked off the heater core with clamps so no water could get in. Even if there was a problem with the control valve, the core was not getting any hot water.
Good job figuring out your heater control problem. Thanks for sharing. We all learn from each other.
