Question about Coleman Mach III Air Conditioner

1 Answer

A/C runs for 10 min then throws breaker

In 87 Bounder - when plug in 30 Amp they run for 10 mins then throw the main breaker. Air is cold when running and you can keep resetting the breaker and it runs again.
Unit has been in storage for three years in AZ
The control box where the breakers are does get very hot to the touch.

I plugged the unit into our house 20 amp when first bought it and they ran for couple of hours before throwing the breaker. When I ask the service man that checked the rv out he stated that was because I had it plugged into a 20 amp breaker ?

Not sure what type of service shop to take it too. We are currently at a campsite - first time we have used the rv - and of course in MEM so hot and humid.

Appreciate any info

Thanks
Ron

The 30amp breaker is bad but when running on a 20 which is good its not enough of amps to support thats why it ran for 2hours before it ..so try changing that breaker to a new one

I believe I might need to change my (20 amp) breaker switch that is running on 10-2 wire which supplies power to my Rheem Classic 10 Seer. I'm not sure if I need to have 220V of power on a 30amp...


Hello, the unit runs on 220 volts that's why # 10 wire must be used. The best bet is to use a 40amp breaker for 220 volts, gives the circuit more protection.

Unit may pull as much as 17-18amps when compressor starts up, but level out to 12-15 amps when up and running. Keeping in mind that is all relative to proper 120v incoming voltage, heavy enough wire to run the application etc. If your AC unit needs cleaning , it may draw an extra amp or 2 . With that said, when your at the park, first thing I'd question is their incoming voltage to RV, and try running fridge etc and anything else on propane if possible. The AC alone should not cause 30amp at source breaker to trip, before 15 0r 20 amp breaker in RV that is connected to AC trips. If it doesn't trip your breaker at home, and all is connected same at park, then I certainly would suspect bad breaker or voltage/wiring at park is the cause. P.S. I noticed you said you have 12 gauge wire (rated at 20 amps) connected to a 20amp breaker at panel, but RV is plugged in to a 15amp receptacle, I will assume with a 15 amp adapter from 30 amp plug. Do you see any hazard regarding 15 amp rating on receptacle? ( just a little advice.)

Have Goodman GDS81155CNA, throwing open high limit relay. Have to pull main breaker to get to reset. I have already taken the entire furnace apart and cleaned it (completely, motort, evap coil cleaned,...


What about the safety limits for over heating? You have tackled all obvious problems, I am only throwing this out there because while the high limit is jumped out, to get the open high limit is definitely strange. So i would be tracing my wiring backwards from the relay to see what else is in line with it. This is not a solution but only a suggestion before running out to purchase the main control board, as most places will not accept a board back if that is not the culprit. Good luck with this one it leaves me slightly puzzled??

I have a campbell hausfeld 60 gallon compressor 20 amp motor what size breaker should be used


I am not a master electrician but I was an apprentice for 5 years and think you should be ok with a 30 amp breaker. anything less and you may be resetting the breaker when the unit first turns on. Dont forget 30 amp breakers will require # 10 wire or larger, #12 just wont do.

AC runs for 5 minutes and then circuit breaker


What else do you have running on hydro while AC is running? Such as coffee maker, microwave, water heater, fridge. That 30 amp breaker is your main breaker I assume, or breaker on pole your plugged in to. Keep in mind your AC will normally draw approx. 15-17+ amps momentarily when compressor kicks in to cool, then drop back to 12-15 amps when running normal. If your AC is drawing too much current, then you would only normally trip 20 amp breaker for AC in your panel. Try switching other appliances to gas operation while running AC, such as water heater, and fridge. Make sure incoming voltage is up to specs as well . (115-120 volts)
If water heater takes 5-8 amps, and fridge takes same when they are calling for power, you'll be close or over the 20amp mark when you consider your on board converter etc. as well. That only leaves approx 10 amps for AC that requires approx 15 amps to run, and up to 20amps when compressor kicks in. If you switch all those other items over to propane, and it still happens, then a current draw test should be done on AC unit to see if perhaps a capacitor is faulty, or possible compressor faulty.

Blows cold but shuts down no freeze up


Check the capacitor. It should be a dual capacitor , runs both compressor and fan. This sounds like your problem only because both the compressor and the fan go out together. Good Luck Hope I helped

Throwing breaker


Throwing the MAIN BREAKER should not happen. Calculate the distance to your main box. Tell me the wire gauge or breaker amperage. Whatever you do, do not get a larger breaker! If its a breaker on this unit Its probably doa with current leak possibly. DO NOT USE fire hazzard IF SHE TRIPS!!! let me know if its your main breaker inthe house. Hopefully you dont have crappy cloth wiring.

Dryer is flipping breaker after 10 minutes into dry cycle.


You have a weak circuit breaker . Should be a 30 amp or higher . If you have access to an amp meter , split the dryer cord , separating the 3 wires (do not remove the insulation ) . If you have a black round cord ( 4 prong ) , carefully slice into and remove the black insulation in a small portion only . Check the amps on both outer wires while running dryer . Make sure the amps being pulled are lower than the circuit breaker amps . On a black cord , test the black wire and the red wire amps . If the dryer has a short , it would not run for 10 min and then throw breaker . It would be almost imediate . A bad breaker will gradually get hot and then flip , but check the dryer amps anyway to be sure .
