air conditioner problems
1999 Fleetwood Discovery 38 ft. So I'm minding my own business sitting in the RV with both front and rear A/C units running. Suddenly the coach fills with smoke from the air vents and the A/C units stop working. It happened so fast I don't really recall what noises they made, but now nothing on the climate control on the wall lights up or makes anything work. No fan motor, no clicks, no lights, no nothing. The rear unit was still making a sound like the compressor was running, but no fan. So I turned off the breakers to both units. When I turn the front breaker back on,....nothing. When I turn on the rear breaker, it still sounds like the compressor is running, but no fan. I can't find any blown fuses, and the breakers did not initially kick. It's getting hot in here. Any ideas???1.3KViews0likes8CommentsRe: 1999 Fleetwood Discovery 38 ft. battery relays
Thanks to everyone who replied trying to help. Turns out it was a simple fix. I had tunnel vision focused on that relay and control board. I just didn't notice that somehow my converter had been switched off, therefore the batteries weren't being charged. No telling how long that had been going on. They had been hot enough to start the coach and move several times, and charge off the alternator, but it finally sat long enough for that relay to start acting up. I put all batteries on a charger, and turned my converter back on. Amazing how everything works now. And apparently that board does drop the relay voltage to 6 vdc once it energizes. Thanks again.785Views0likes0CommentsRe: 1999 Fleetwood Discovery 38 ft. battery relays
Update. I took the relay apart and cleaned the contacts. Nothing really looked out of the ordinary, but I put everything back together and for the moment it's holding. But I did notice that the trigger voltage for the relay coming from the battery control board is 5 vdc and that's a 12 vdc relay. Does anyone know if this is normal?785Views0likes0Comments1999 Fleetwood Discovery 38 ft. battery relays
Recently I noticed a "buzzing" in the back of the coach when it is parked, on shore power, and both battery relays are in the on position. I finally found it in the battery compartment, and it was the 200 amp. SPST relay mounted on the wall of the compartment. I tapped on it and the noise temporarily went away, but later returned. Then I started the engine, and the 12vdc house lights came on along with the running engine, but then both died. After 3 cycles of this the engine and lights remained on, but that relay is now oscillating on and off when both the battery relay switches inside are turned on. Not knowing what's going on I am leaving both relay switches off until hopefully someone here has an idea what's happening. Is the relay now bad? I see it has a bolt head on top and thought maybe I could open it up and clean the contacts?? Any ideas are appreciated.2.8KViews0likes13Comments
