Trouble shooting

[lacrista681]

Hello everyone... I am new to the forum. I have a 2006 Sandpiper T34SP. We love it. Went to the lake last weekend and plugged into campground electricity. I went to turn the AC on and the whole main control board popped three relays...Can someone help in what could have done this? I would like to check as many things as possible before I re-connect the new one and this happens again. They are $300 a pop.

High park power? At least that would be my guess.

Did you have a surge protector installed when this happened? If so, what did it tell you? If not, then perhaps there is something wrong wth the CG power supply as suggested.

No I did not have a surge protector. I will have my husband to check the amp out of the campground plug in.

Don't know much about toy haulers, so this is new to me.

Initially, I thought you meant circuit breakers, but they don't cost 300.00 each (the entire power center can be replaced for under 200. (8900 Series Electronic RV Converter Center, 65 Amps - $184.95)

So, someone help me. What went wrong; where are the 3 relays; and why did it cost 900 dollars to repair/replace them?

If everything was OK until you turned on the air, you might have overloaded the campground's supply (if it was only 20 amps), or if there was a problem with the air, you should have blown two circuit breakers at most (main and air conditioner) and they don't get replaced; just reset.

If you have a 50 amp service camper plugged into a 50 amp supply and there was an open neutral (such that your camper was supplied with 220 VAC across the power center instead of 2 110 circuits, way more than the power center should have blown (like the air conditioner, microwave, etc).

In any case, it would be another case for a hard wired (or dangling) surge supressor.

Thank you Lou for the info... At $300 I was taking about the whole converter. In TN we only have 2 RV parts shops. Camping world one and and mom & pop shop. It was about $289 plus tax. I will pass this info to my husband so he can check all this out.

[Herk7769]

Do you have a 50 amp or 30 amp service?

[lacrista681]

It is a 50 amp service.

[TURBS]

Sounds fishy.

[B47]

I should have asked earlier, but did any of your neighbors have any electrical problems that you know of?

[Bttravel]

I'm with Herk on a possible a/c problem. Could have a dead short since that is what started the "popping". You might want to have an electrician do a circuit check and the a/c before more "popping".

It seems to me that if you were to use a surge protector/EMS it would not have allowed the high voltage to enter the rv? I know they are expensive, about $380 with shipping for the 50 amp one, but I would NEVER plug into a campground without one NEVER! It is not just the high voltage that will do harm, low also.
