Question about Coleman Mach III Air Conditioner

1 Answer

I am trying to buy a shroud for my coleman rv ac unit its an older rv 1995 and i have found so far that the shrouds have changed and everywhere i look they want a model number. Any info on the outside have been burned by the Arizona sun. i did find a tag under the shroud that used to have info but its been destroyed by the sun also. Any help with a model number or where to locate one would be great. Thanks Matt

Sorry we have no referral service here or anyway to locate the parts for you. That said my friend had to have his custom made. He is in Calif and I don't know where he had it made.

SOURCE: Older Penguin roof shroud, new style fit?

I just replaced my two 620315.321 shrouds with the newer style without any problems. I went to the Camping World site (and called them) with model no. and they knew what to send me. I also found that they had the best price at $79.00 (member price) with free shipping.

I didnt check your shroud part no.s, but think you will be ok if you do as I did.

SOURCE: Coleman roof top rv air no cool,warm compressor

No Cooling.
Turn the selector switch to “Cool” and the
thermostat to a low temperature (below room temperature).
The fan runs OK, but the unit does not cool. When the unit
housing is removed, we observe that the compressor does not
run; however, it periodically hums for 15 to 30 seconds.

Possible Causes- Check all of this before buying a new unit, that may not be the solution.

“The voltage could be low – ”
a) Check the voltage between #1 on the
overload switch and the “R” terminal of the
compressor while it is not humming. This
voltage must be 115 volts domestic USA
models or 240 volts export/overseas models.
No less than minus 10% is allowable.
b) Check the voltage from “C” or “R” of the
compressor while it is humming (trying to
start). The latter reading will probably be
lower, but it still must be 103.5 volts
minimum domestic USA or 216 volts
minimum export/overseas models.
If the first reading is above 103.5V domestic USA and
the second is under 103.5V domestic USA, there is
too much voltage drop in the lines - a situation which
must be corrected for the air conditioner to perform
safely and satisfactorily.
2. “A capacitor could be shorted, weak or open.”
Turn the power off.
Caution – There is always a chance that a capacitor is
holding a residual charge, so before touching a
terminal, discharge the capacitor as explained earlier
in this booklet.
Remove capacitors, visually examine them and test
them per instructions given in earlier section on
capacitor testing (See page 9).
If the capacitors test OK, replace them and carefully
reconnect the wires. Be sure the wires are connected
to the right terminals.
3. “Start relay contacts could be open – ” if so equipped.
Turn off all power, then check for continuity with
ohm meter between terminals 1 & 2.
4. “Compressor start winding could be open or
Check compressor windings per instructions. See the
section on the compressors (See page 8).
5. “Compressor could be mechanically stuck.”
This very rarely occurs and when it does, it is usually
after a lengthy shutdown. This should be considered
only after all the above possible causes have been
positively eliminated. To free a stuck compressor, use
your hermetic analyzer according to the
manufacturers instructions.

SOURCE: where are the drainage hoses located on a 2005 coleman rv ac

many times the pan of the evaporator in intergral with the drainage. You need to pull the cover and see which way the pan is pitched you should be able to trace it that way.

SOURCE: Dometic Rooftop RV Air Conditioner works as long

Hi, most all a/c that are on the market are designed for that exact temperature, 95*F. After that they will loose up to 40 % of there efficiency. But tripping the breaker indicates it is working to hard and over ampping so there is a problem up top. It may just be a very dirty condenser coil which will cause this unit to build the high head pressure causing the compressor to draw more amps then normal and will trip this breaker. If you can, go up and remove the cover. Watch it run to see if the condenser fan motor is running good. Look at the coil for dust and dirt build up. Its a good sign that it cools at 95* F, so I believe its just a dirty condenser coil. This will cause your internal pressures to peg out in temperatures at 95 and above!.Even if it looks OK, kill the power and run a water hose up top. Was out this coil and watch the dirt run out of it. I have seen the head pressure on units at 400 P.S.I. with a dirty coil and after washing drop 200 P.S.I!! If the fan is running good, this will be your problem. Before you go up, take a good flat heat screw driver along and when you are done cleaning this check the electrical box, and make sure all of the main connections are good and tight. Check to see if there are any signs of burned wires as this will also trip breakers as when loose they will create heat and burn the ends. This will solve your problem. You may want to check the 2- wires at the breaker also, just be sure it is off and tighten just the wires that go into the breaker as they will be dead at that point. Please use caution!. Doing all of this will take care of your problem, I am sure unless you have a internal compressor problem which I don't believe you do. Please don't forget to rate me as I know you will be kind to me. Please keep me posted and I will be checking up on you also. I wish you the best.

Should there be a condensation hose of some sort. I have a leak and can't find where water is coming from

These units do not have condensation "hoses", they have an evaporator pan than is located under the evaporator coil and catches the condensation and then lets it drip down onto the roof and then off the RV. If your AC is leaking into the inside, remove the inner shroud and feel up into the evaporator area for the pan. If it is full, then the drain holes are plugged. They are not easy to get to. Remove the upper shroud and then remove the front cover over the evaporator. At the base of this area is the pan, on each end is the drain hole. Clean them out and all should be fine.

Hope this helps,
