Things not to do while motorhoming...

CORRECTION!

It was the KOA in Junction, not the KOA in Van Horn. Van Horn good. Junction bad.

"And good on your motorhome for being tolerant enough to survive the dirty power situation uharmed."

It notices things before we do, then takes preemptive action. It got us in trouble in a KOA in Van Horn. We plugged in, the shore power didn't come on. We checked the screen inside and it said we had a ground fault.

We were on our way to do something else, so we stopped by the office, told them we had a ground fault, and left. Lots of staff there. They would know how to take care of it, and sure enough, when we got back, the power was on. Trouble is, the next staff person that saw us told us they checked the electricity and there was nothing wrong with it. Who cares what the problem was, it works; but they got pretty pushy about telling us we reported a problem that wasn't there. Every staff person we met after that began the conversation with, "Oh, you're the people who said they had an electrical problem but didn't". Apparently we had attacked the integrity of their park and offended the whole lot of them.

I blame it on the coach.

Great troubleshooting! And good on your motorhome for being tolerant enough to survive the dirty power situation uharmed.

Well, it’s not like we decided to do it, we certainly didn’t want to do it, but we had to troubleshoot the furnace today. It’s not the first time we’ve had to troubleshoot a furnace. Several years ago, when we had a different motorhome with a propane furnace, it quit and we had to get it fixed. As I recall, a repair guy had to replace the furnace motherboard. Within a couple months it failed again, in a different state, and a repair guy there replaced the limit switch. That took care of it.

But this is different. This is a hydro-hot furnace. It runs on diesel. It’s supposed to run on diesel anyway. It has always run on diesel before, but Judy got up at 6 and it was cold in the front room, 55 degrees, so she turned up the thermostat. Nothing. She turned up the bedroom thermostat. Nothing. She got analytical on it. It runs off the same diesel the engine does. She turned on the key and checked the fuel tank. Plenty of fuel. She turned on the hot water (the hydro-hot system serves both the furnaces and the hot water). The hot water was hot. She ran the water for a few minutes. It stayed hot, so she knew the problem wasn’t the hydro-hot burner, but some control that triggers the furnaces. She got out the manual for the hydro-hot. No help. She went outside and looked in the cabinet the hydro-hot lives in. No reset button. Still no heat. Can’t turn on the heat pumps; they don’t work at all below freezing and really don’t do much until the outside temperature warms up toward the forties. She turned on the little electric space heater in the front room and came back to bed.

After she warmed up, we both got up. We flipped any breaker in the control box that looked like it might help. Nothing. It’s getting colder. It’s snowing outside. Checked out the electrical status display. It said we had an open ground on the 30 amp shore power. That shouldn’t affect the furnace; it runs on 12 volts. It shouldn’t be the electrical power; everything else in the coach is on. Of course, if the 120 volt power goes out, the inverter just takes over and runs all the 120 volt stuff off the batteries. That complicates the analysis. Checked the inverter display. It said we had high voltage on line 1. Still shouldn’t affect the furnace, but we’re starting to suspect an electrical supply problem. Let’s bypass the shore power. Turned on the generator. 50+ amps of 240 volt power. No help.

One thing left to try. We’re getting error readings on the shore power; let’s disconnect it completely. Victory! That was it! Dirty electrons coming out of the campground power source! Dirty power.

All systems go. Hydro-hot burner cooking. Heater fans blowing. A lot of space to warm up, but within an hour we were toasty.

Life on the road.
