New Member Monty with 2005 Journey 36G

[mwilson9]

I have purchased 2005 Winnebago Journey 36G with a 300 cummins.
It only has 12,500 miles,however it has been sitting under a shelter for 4 years and not been cranked.
First the good. It was a one owner and had only 12,500 miles.
The bad. It had not been cranked and the tank was almost full of old diesel and it had jelled. Obviously I had to replace all of the batteries, cranking and house batteries.
It cranked with no problem but surged. I was so consumed with the surging, i didn't adequately inspect the entire coach, because i knew the people i was purchasing from, I assumed all was operational.
The coach had to taken to a Freightliner Chassis shop to have the fuel issues fixed. As it turns out the fuel had sit for so long it had jelled and stopped up the "fuel strainer" which is located in the chassis behind the rear tires. I had already replaced the "fuel filter/ water separator" in the back and that had not helped.
They had to drain the tank and replace both the strainer and the filter.
I'm back on the road but now i'm finding the coach heat will not come on. I took the thermostat off and re-installed it and that didn't help. The AC will work and the fan for the AC comes on but the fan for the Gas Heat or the Elec Heat does not come on. I found the exhaust ports for the heat near the hot water heater but not any access to the heating unit itself to check. Any suggestions would be appreciated.

First collect some ideas of things that are not right! Then look at that list and decide on what is a priority to work on as a way to cut the obvious confusion that comes with working too many issues at once!
Sounds like electrical as a start on getting many of the other RV issues started!
consider how important it is to get the right commands? The Electrical system for the starting and the coach are where those commands start and they have to be right for the item to work correctly!
Like fighting a war, the orders have to be right to get much done right!

In that light, getting the RV engine to run can be a great place to start as that lets the engine /alternator give you good power when running.
But that system is running, it is also connected to the system that does the RV coach items like inside lights, vent fans, and control and fan on the furnace!
furnace won't run if the there is not good battery power, but engine running should give that and you can then begin to look at what else might be a problem with the heat---if that is the chosen priority!
A way to search out good reliable info may be as big as any, even though we can lend a hand on details. The details we can pass along mean a lot more if you have looked at the manuals and know more about where things are and what to expect when using them. Like on a radio, it's easier if you know which buttons to push!
Winnebago homes site as there is a ton of info under the "owners" tab:
https://www.winnebago.com/
Knowing how to set the thermostat and what to expect is a biggie, so that you can listen to what the furnace is doing.
If the electrical is all getting to the board at the right time and places, things usually go like this when trying to heat:
1. Turn the thermostat to heat setting with the fan on auto.
2. Set the temp high enough to call for heat. The blower should come on immediately on RV. Different than home furnaces which have a delay!
3. The fan should blow for a short time (30 seconds?) then the gas valve should open. if quiet, you may/may not hear a snap as a gas valve opens? This time allows for a safety item (sail switch) to sense that there is good air flow! No filling the furnace with gas if the air is not moving well!
If air is good and gas flows, it should then light and continue heating until the thermostat says enough!

One of the big issues with RV and setting is that wire connections often corrode and stop passing the power!
If you locate the outside cover for the furnace, look for a brand and model number. That is a good place to find an online manual for the specific furnace you have. It will have a chart and show where different connections are located. Look at those connections and perhaps wiggle them around to make sure they are clean and making good contact as a simple start!
If you use a meter to find if the 12VDC is getting to the furnace, that will help sort the problem as it might be other things like a dirty connection on the other end or perhaps a blown fuse. That helps sort which end of the bus to work on!

Best of luck in the chase and let us know when we can add more.

I am going to say you have a basement ac/heat pump, if that is correct here are my thoughts.

If you turn thermostat to elect heat you have to set it to within 5 deg of what the temp read out is. i.e. reading 65 set temp to 69 then increase as needed. Sometimes it takes a few seconds for the fans to kick in.

If you set temp to high the gas furnace will come on automatically until temp is reached.

If you turn thermostat to gas heat then the gas furnace will provide the heat.

Have you checked the propane level? Does the stove work? reason will show propane will flow. Another check does the water heater work on propane.

Good Luck
