That cover is not hard to remove. Remove it and check for obstacles first, while it is off :>) I had one do that as it had about a pound of dirt dober nest on the shaft. If that's not it, cut it on and when it stops, cut the power first, and then check to see how hot the compressor is. If it's real hot, try recharging.

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.

Maytag Performa Bottom Freezer, Compressor buzzing.


compressor pulling locked rotor. what your hearing is your current relay energizing. compressor goes off on internal overload protection and then tries to restart a few minutes later. unfortunately compressor needs to be replaced. sometimes a hard start relay will free rotor up. it can be purchased at a refrigeration supply house.

Suburban stalls while driving after running for 15-30 minutes. After letting it sit for 5-10 min it runs fine for another 5-10 minutes, then starts doing it all over again.


a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

After driving for 15 minutes truck stalls,restarts no problem ,but trans races and stalls again. if it sits idle for 2-3 days runs again no problem ,until the 15 minute drive again .the 15 minute drive...


put a OBD II code reader on it see if it has stored any codes if not replace the TPS sensor and the MAF sensor do the replacements at different times so you don't buy one or the other for nothing

What you think it means is exactly what it does mean. When a running unit is shut off it should not be restarted until the system pressures have had time to balance out so the compressor can restart without difficulty.
