RE: Heat & A/C on at the same time!

Find a good the to sort out the thermostat/controls. Our has two furnaces and two heat pumps. It is cold with the heat pumps selected , the furnaces still come on first to bring the coach up to warmth fast, then shuts off and the heat pumps take over. Our Holiday Rambler Fifth Wheel operated the same way, I believe. And when it gets so cold the heat pumps aren't able to keep up the furnaces kick back in and heat pumps go off. No way a heat pump can blow both hot and cold at the same time, unless it also has heat strip and it is wired cockamamie, with it wired on the wrong side of the thermostat/switches. Heat pumps work in both direction reversing the ac cycle on heat to extract the heat from the air outside and heat the air inside but can only work in one direction at a time. The OP said it was a new trailer to SIL and was getting heat and AC at the same time out of the overhead ducts. It seems to me the AC is running in the HP mode and the new owner doesn't understand that the air conditioner is capable of producing heat or cold depending on the mode.

RE: Heat & A/C on at the same time!

Perhaps it's like mine. My T-sat has a selection for 'Furnace' and in that case the furnace will come on and blow out of the lower furnace ducts. Also, I can select 'Auto' and in that case if the T-stat calls for heat the AC comes on and works as a heat pump blowing warm air out the upper AC ducts. If the trailer is warmer than the set temperature the AC blows cold air out of the same upper duct. Sorry, not correct. AUTO does NOT turn on the Heat Pump function if you have a AC/HP upper unit. ALL AUTO does is allow the system to select the fan speeds and shut the fan OFF when temp is met. You still have to select HEAT PUMP on the wall tstat for the HP to function if you have one. If you do not have a HP display on your tstat, you do not have a HP. Doug Doug, My AC does operate as a Heat Pump or Air Conditioner. In the 'Auto' Mode it will turn-on either function. Below is copy and paste from owners manual. G. “AUTO” - Auto Change Over Mode In the AUTO mode the system will automatically change the mode of operation from cool to heat or from heat to cool. In order for this mode to operate, the zone being programmed must contain either a heat pump, heat strip or furnace heating source. When in the AUTO mode, all pre-programmed operations for the heat pump, heat strip, and furnace will apply. NOTICE it states the MODE MUST be programmed for that to happen. I will bet you have a CCC2 Dometic wall tstat. On your tstat, IF NO OPERATIONS PRE PROGRAMMED, then the system will NOT auto switch between AC and HP. So, if NO programmable Tstat(very RARE to have one), then the AC/HP will NOT switch between the 2. Doug I'm not sure why you contiue to insist you know what I have and think I don't know. Please watch the video. Dometric Thermostat in 'Auto Mode'

RE: Tried towing after new tires & algnment...it did not go well

My F-250 was a perfectly driverable truck untill I replacd the OE tires with BF Goodrich All Terrain Tires. It gave the feeling I was sitting on a basketball, and especially going through a curvey road was a white knuckle experience. I thought they might get better with some miles on them, but after drving from Montana to Florida pulling a Fifth Wheel I gave-up and traded the truck in down there.

RE: Fed up with tire blow outs!!!

This is my first RV so still learning everything. I have not had the tires balanced. One tire dealer did suggest going to 15" tires, he said those are much easier to find in D or E rated. But then I would have to get all new rims as well. I did not check the tire pressure before I left for this last trip this weekend. Guess that's another check list item before getting on the road. These trailer tire issues have been going on for years. I would follow this tire dealer's advice and go with the 15" wheels with light truck tires

RE: bubble on EPDM roof by the seam

Leave it alone. Never cut a perfectly good roof covering that is not leaking. Often times those bubbles come and go with temperature changes.

RE: Pulling more than 50 amps ?

If the loads were perfectly balanced and wired as 120/240, there would be 0 amperage on the neutral. If the receptacle was wired with the same 120 volt leg on both, there would be 100 amps on the neutral. Finally, a good explanation .

Park electrician is correct.

RE: AC problem from hell: Now compressor is turning off.

My Coleman AC has a low voltage cutoff if the campground voltage drops below 109 Volts.
