Question about Coleman Mach III Air Conditioner

1 Answer

It runs cold briefly for about 4 to 5 minutes then

I have a Coleman air conditioner mounted on top of my cruiser, model 6759C707. It hasn't been used much in the past few years. It runs cold briefly for about 4 to 5 minutes then stops and the breaker panel trips. It sounds like the pressure builds and then it stops. It runs good and cold, I am thinking that there may be a rusty electrical connector for a pressure relay inside the cover that is corroded that I am going to check for. The fan blows good without AC an runs a long time. Could you tell me what to look for?
Thanks,
Harvey

Check the compressor capacitor. It would have gone weak. Replace with the identical value and type.

I have a 2010 30' cougar travel trailer, we have never used the air conditioner which is a coleman mach model, when I put it on auto and cool it blows cool air but never gets cold am I suposed to


Check the temperature of the air coming out the vent If it's more than 10 degrees below the air going in it's ok. If it's the same temperature, the condensing system may be not working. The compressor may just be a quiet one!

I have a coleman roof top a/c with no wall thermostat. can i put one on it? not sure which model i have. are thre some models which a thermostat cannot be installed on?


Yes, you can put a thermostat. Doesn't it have a cold/hot selector? The fan may still run when you turn it to warmer, but it limits how much the compressor kicks on and off. You will need to go to an electrical supply and tell them what you are doing, and whether or not they recommend you use a relay or wire into the one already in the unit.

Fan not blowing in coleman trs rv roof air


well check a few things first....have someone remove the cover and reach in with a hand and try to manually spin the blade...free spinning?....then tell the person below to click in the on postion while someone views from up top.....is it humming? or even trying to spin?....if not check the fuse on the RV that protects the A/C unit.....good?.....now replace the capacitor ( it the silver or gray can looking thing that the motor wires run to) only the correct size will work w/o causing further motor damage.

It worked fine last year. This year it throws the breaker on the gen. After 2 or 3 min. The fan works on low and high but it trips on low or high ac its a model 6759c707


If all is the same as when it ran good, such as same power cord (no extension, or properly sized extension ) same generator output voltage etc, then I'd check amp draw when compressor kicks in. Good chance compressor start capacitor may be faulty.

2 year old Coleman Mach III tapping and not blowing cold air:


Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned

My coleman 13,500 roof a/c year 2000 does not blow as cold as used to. I have cleaned the top condenser coils, with no help. It also at times will seem to pull a heavy load when I assume the compressor...


if the compressor started and stoped means
1 thermostat need settings
2 compressor over heated due to low suction pressure need to check and repair the leak then charge the freon
