1991 Liberty H3 40

[Judi Brown]

We have had this coach for 6 months and I want to start wabasco and not having much luck. Where is it located on coach. Jud.

Jud,

Just a guess, as I have '97 Liberty, but on mine it's on a rocker switch on the left side of the dash. Then there should be a couple of thermostats (looks like the type in your home) that control the individually zoned heaters.

Hello Judy

A couple of questions.

When you turn the switch on do you hear anything? If so, what do you hear.

Have you considered calling Liberty? Almost every bus has plumbing a little different and there is for sure some ball valves among other things that are incorporated into that system that you need to learn about and they will have all the answers.

Judi,

If the bus has been in warm weather and the Webasto not used in a few years you might need a little maintenance.

Traditionally the nozzle has tendency to get clogged, it's easy to change and only costs about $21.

There's a basic Webasto primer on my website and it will show you how to change the nozzle.

Since you're a NOOB (newbie) most the guys here (and Debi) will be glad to offer you assistance. More details and info about your problem/issues the better.

We turn on switch marked webasco and don't hear any thing. I think I got some bad fuel as had to change filter on gen. twice in short time and drain
raycor for motor. If I can find it, I'll change filter and knozzels.
Jud:rolleyes:

Judy it sounds like there is more at issue here than a filter.

You should be able to here that unit running weather it is burning fuel or not.

[Jon Wehrenberg]

Judi,

When you turn on the Webasto (at least on my coach) you should hear several fans inside the house, and outside near the Webasto itself you should hear a circulating pump.

If you have a plugged fuel filter you should still hear those components run. If you have corrected the fuel problem, but not run the Webasto it is unlikely the fuel filter is an issue.

You do not say if you have a 12V house or 24V house, but step one in my mind is to determine if the Webasto electric circuit has power. Check for a blown fuse, tripped breaker, or if a 24V house a bad relay at the Allen Bradley circuits.

Also check to verify that the thermostats which control the Webasto inside the house are set to a higher temperature than it really is, and also check to see if there is a switch lever under the thermostat, and the switch lever is pushed all the way to the right. That is an on-off switch.

I know this is coming at you like water through a fire hose, but it is all related to insuring you have power to the Webasto. Nothing else counts at this point.

Let us know if you have any questions, and provide us with as much informatin as possible. Mango and JDUB are experts at what is inside the Webasto, but they can't help you correct the actual unit until you have power to it.

Where are you located? Maybe a POG member more familiar is nearby.

[JIM CHALOUPKA]

Judi, to help the helpers; you said you had the bus 6 months.

Do you know for a fact that the Webasto was working properly in that time period?

Oh yea welcome to the group. Sometime the water gets hot:rolleyes:

When we turn on webasco, we hear fans running, but know heat. I mite not be setting thermostad right. I was turning bottom lever to the left thinking it was for air conditioner. We live in Vancouver Can. and bus was parked in Cal.
We never tried it till now, we did not get very good manuals for it and has been a learning period. We are new to this board and finding it more helpful
than others we have used. Judi

[MangoMike]

Hi Judi,

If you're hearing fans, I'm assuming they are the fans inside the bus. Can you walk around to the rear of the bus (usually the location of the Webasto) and with the engine off and the switch on for the Webasto see if you can hear anything.

Typically the Webasto will try to start, (if it has electricity) but if it doesn't see any flame in the burner it will shut down to prevent over saturating the burner with fuel. It would be nice to know if at least it was trying to start in that 2 minute period.

I'm not familiar with Vancouver, but if you have a sizeable Marina around you, they are used to working on the Webasto (or AquaHot - which is basically the same thing.)

Judi, to supplement the manuals you didn't receive with your bus purchase, click on Quick Links, click on POG Home, and at the home page on the left click on articles there are three pages of info that will help you a lot to get a hold on what you have.

Judi: I also would like to add to the info here that the webasto heat is not instant. The water supply has to heat up from the furnace before you feel the heat. Only if the coach engine is up to operating temperature are you going to feel heat from your heat exchangers.

Good Luck.

[garyde]

Hi Roger. Mine only takes 5 minutes to feel the heat after I start the Webasto. That is from stone cold including engine.

[rfoster]

Gary:
I know you have a Liberty and they heat up and better than others but it ain't like lectric - ya know what I mean. Mine takes 4 minutes 58 seconds.:cool:

[JIM KELLER]

Roger, Mine heats up faster than that. I can name that tune in 4 minutes and 45 seconds.

Hey Guys, your forgetting, Judi doesn't hear anything!
