Things were working fine, the firs t few times we needed the ac. But when we came out of Vegas, we stopped for lunch and utilized the genny. Ac worked fine. But that night we discovered that it had popped the breaker. Before we shut off the genny, I made sure that the ac had cycled off,then shut it off. This has occurred randomly for the rest off the trip. I always make sure to not stop the ac in mid cycle prior to shutting down for travel. We don't unplug the shore power till the ac's have cycled off and the switch has been moved to off. Yet the #1 ac will pop the breaker. I have never had this problem in my other coaches. Any suggestions?
Thanks in advance. Ps. Prior to this trip, coach had been seen at FT of Tx where we purchased her.
Does it appear to only happen during a driving session? If so, and the breakers are on the foot of the bed, it might just be a tired breaker that trips due to heat and/or vibration, especially if it's towards the bottom of the breaker panel (closer to the engine). We have had to replace 3 or 4 of them over the years, starting with the bottom ones and working up. In an '03 they're a common GE breaker from Lowes. Not sure about a 2012.
The breakers are suspect. We have had to replace them as well. Get a spare while you are at it. If you change it yourself be sure the land line is not plugged in and the inverter is off. And then double check. Not hard to do at all.
I have replaced my #1 breaker twice. Last trip it worked fine on shore power but on the generator it kept popping the breaker.
Anyone know why only the front AC does this and not the other ones?
While checking breaker make sure connection is tight. Loose connection will cause breaker to trip
Hi Darrell,
Possibly you have a weak circuit breaker if it shut off often or you have low voltage. Though this is not a great test, does it feel soft as you switch it on and off?
The front AC has the longest wire run back to the breaker box. The will cause a little more voltage drop and a little longer surge to get the compressor started. When on the generator, try always starting the front AC first, when generator voltage will be highest without any other loads. The highest surge is at turn on, starting both the fan and compressor. Once on, the fan is running, and just the compressor cycles.
Probably a long shot, but if the capacitor(s) are bad, the start up load will be increased quite a bit.
Something that is not too difficult to check. Remove the roof A/C cover and then (yes, with power OFF) the cover for the electrical compartment.
Check capacitors for discoloration or leakage. Check electrically ONLY if you are safe and familiar with capacitors-- they store quite a jolt.
I will try that sequence. Still confused on why it does not trip on shore power.
Good thing to check, Thanks
Check the connection where the Airconditioner and coach wiring come together. The wire nuts on mine were melted. But it never tripped the breaker!
Only on the generator?
It might be worth checking the cycle output (60 cycles under some load) of your generator.
