.....I have been "chasing" WHY my Webasto will not fire and, in final exasperation, carefully took the control box apart and found the reason....a component in the lower right corner of the board was no longer soldered to the board and was broken off at the resistor, or whatever (same part). Wonder if anyone might know of.. 1) a replacement part ( box, board or???? ... 2) a replacement board or ...3)have any suggestion that might help me avoid a $415 part from Webasto????? Thanx, Mucho"  RCB '64 Crown (HWC) | ||

RCB The place that Is missing the solder can be replaced on the Board, Go to Radio Shack with the Resister explane the problem to the guy that Is working behind the counter and If he Is anything like the one that works here he will give you a new Resister that will work In place of the one that was In there, Very carefully take a Piece of solder and put In the resister and you are In business.

At $300 for a new board, I'd repair the old board. Sometimes broken resistors (if it melted the solder, the resistor or split the resistor) are just a sign that something more serious is causing the Totally Impossible To Sustain Usual Performance symptoms. By the way, if anyone has a Webasto thats TITSUP, and not rotted out, let me know, I'll make you an offer. Gillig-Dan | ||

Today I took the board to a local repair service and for 15 bucks, they replaced the kaput capacitor, soldered several joints on the board that were defective and spent a bunch of time just chasing the problem. All seems to be great with the board,..... But the Webasto still won't flame. I've chased the thing from here to next week according to the service manual and have eliminated all but a possible injector problem. Got fire across the electrodes, have a cone shaped spray of fuel, the voltage checks out everywhere and just flat don't know what else to "chase" Ordered a new injector tip from Vehicle Systems ( $14 +) and am awaiting arrival for installation. Thanx to all for your remarks and e-mail. I'll post when the problem is resolved....meantime, my wife's mother passed on this morning and I am making a "flying" trip to Louisiana in the coach ( 1300 miles one way )and counting on the engine heat to furnish hot water ( marine HW heater).

I'm sorry for your loss, R.C. It will be 14 years May 25th for me. My prayers are with you. Drive safe, she may like the company, but she'll still be a bit disappointed, as will we. Onward and Upward Marc Bourget | ||

If you have spark and fuel, the only thing left is air, right? Mud daubers? Gillig-Dan | ||

Many, many thanx, for the kind and thoughtful words Marc and Jim. As it turns out, wife is in LA....Coach, dogs and I stayed home. Funeral is tomorrow....just no time to drive that distance and be "on time" for the services; takes about 20-24 hours depending; can do it in less time, but not comfortably ( I'm listening to you guys!!) ....Thanx again. Jim-Bob....thanx to you for your suggestion. I am pretty sure the combustion air is clear, BUT...will check it out when I install the new injector tip. Interesting that the board can be fixed pretty easily, but Vehicle Systems says they will not open them up to find the cause.....just sell you a new one.  Sheesh! I'll keep the information going until the thing is "fixed ". Webastos are too expensive not to share information FWIW RCB | ||

when installing the ignition electrodes they must be positioned using adjustment gage 310.646 which is normally attached to the outside af the burner. have you changed the fuel filter? this may reduce fuel flow but still have enuf so you could view the sray pattern. i have a service training manual that has alot of other stuf to check if you need it let me know. joe | ||

Burner controls are usually designed to be idiot proof. If you try to defeat them or make any modification to them they refuse to work. They are repairable by a knowledgeable person who can trace out the circuity and perform proper tests but this takes several hours and at $75.00/hr can quickly eat up the price of a board. Everyone who uses a Webasto should have a spare control box. If your unit doesn't work, just plug on the spare control. You have an instant answer if the problem is in the control box or external. The nozzle is also critical and if the spray batern is not correct (from dirt inside) the burner will not light. Therefore, you should also carry a spare nozzle of the correct size. Fuel pressure, air flow and burner efficiency are best done by a dealer who has the proper equipment. | ||

"best done by a dealer " GAWD, I hate when they tell you that. Especially when the dealer tells you it's not repairable and it'll cost you your arm and left leg to replace the defective part....... only to find out it's not the part at all, that's bad.. With all of the standard RV propane heaters, low or reduced voltage to the blower will result in the heater refusing to fire up. Make sure you have a fully charged battery with absolutely no less than the required voltage going to the burner. Failing to insure that, almost cost me the price of a new board to replace the so-called "defective board" the dealer's test indicated. | ||

Well now, Stan... while I appreciate your remarks and your approach to the problem, I wonder just how many of us in this hobby can really justify (afford) to carry an extra $415 control board around in the spare parts box....? My guess is that an extra injector tip would be wise , but how often would one run into that problem in this use. A full time road vehicle, probably, but a 10,000 mile a year coach?....I don't know. I suppose one could say the same about almost any system device on board, including inverter, generator, water heater, fridge, etc. As a practical matter, the Webasto, in my case at least, is a convenience item and not a necessity. Maybe I'll go out tomorrow and buy a couple of extra batteries for starting and house use...... ...get my point? Don't mean to be unkind, but there is a limit, at least in my case, how far one can go with extra stuff....Social Security is what keeps my ship afloat. Thank God I've got it. The new nozzle arrived today and we shall see what we shall see. And I am checking for daubers.... Thanx. RCB | ||

And folks wonder why I usually recommend Propane. The entire 42000btu furnace unit doesnt cost what a "perhaps it might work" circuit board for a modified truck heater does. Caviat Emptor, FAST FRED | ||

What you carry for spare parts depend on how critical the system is. If you are a boondocking type, then you should carry a spare board for your refrigertator. Otherwise, you will have to drive from your isolated location to a city with a repair center that is open. This can totally ruin a long weekend or two week vacation. If you do not have a backup heating system when travelling in cold weather, you need to able to repair it. If you don't travel in cold weather then the Webasto was a bad investment in the first place. As a matter of interest, I have the technical ability to troubleshoot and repair a Webasto control but I still carried a spare so that I could repair the faulty one at my convenience. Most of us have a limit on what we can spend and everyone makes their own choice. A few hundred dollars of spare parts can make the difference between an enjoyable trip and a nightmare. This has been discussed on BBS before and one time people published their list of tools and parts that they carried. The people who did their own conversion invariably carried the most. | ||

"A few hundred dollars of spare parts can make the difference between an enjoyable trip and a nightmare". A few hundred dollars of spare parts is probably the difference in my having a trip at all..... I get your point Stan, but redundancy can get out of hand,,, and for me, that would be the case in spare parts for all systems. I just completed a 7,000 mile trip to Halifix, NS-----didn't hook to shore power one time, made it all the way with a change of starter (not unexpected) and two new outside Tandems (unexpected) due to a puncture in the sidewall of each, a couple of new genset plugs and a dumping tanks about three times....no complaints. I carry belts, antifreeze, extra fuel, bulbs, fuses, and lots of tools, plenty of food and liabation, TP, an electric blanket and an extra small TV. Beyond that,if something occurs, the LORD probably didn't want me on the trip anyway. I carry good tow insurance and am old enough to know that things don't always go as planned....or as wanted.... Maybe you could send me an extra control borard for the Webasto..... Works for me, as FF says. Thanx for your input. ( I'm serious) RCB '64 Crown Supercoach (HWC) | ||

RCB: If you re-read my post, you will see that I referred to critical system parts. It is now five days since you posted about your Webasto not working. If you just returned from a trip to Halifax, you probably were in some below zero weather. Five days without heat would be a disaster in those temperatures. Not only could you not live in the bus but the entire water and waste systems would be frozen solid. If a few hundred dollars is the difference of a trip or no trip, you may have got into a lifestyle (hobby) that you can't afford. What is your plan if you blow an engine while on a trip thousands of miles from home? Over the last twenty-five years I have spent hundreds of hours helping bus nuts repair their junk. I have supplied parts free and patched things that were beyond repair. I had to draw the line at people who wanted me to make their brakes work when there was nothing to repair except a completed replacement of everything in the system | ||

Stan, I thank you for your remarks,.....I think. Would have sent you an e-mail, but I see you are excluded (exclusive?) and cannot be reached directly from this board. Seems to me "Critical Systems" has to do with anything that makes something work.....or not....at an opportune or better stated, inopportune time. Wouldn't that be the case for most anything in life? From what you say, I....and possibly others, should reconsider my choice of hobbies. This hopbby that I have indulged in is definitely not a lifestyle. It is an interest. It is not my goal in life, it is something that I (we) enjoy and it will never be a consuming thing in our lives. Meantime, I apologize for posting something offensive to you. Our coach is paid for, is what we feel we can afford and if it should be that the Good LORD decides I should not be involved in this pursuit, I will not cry about having to give it up. I do not consider our coach junk and frankly am not real tickled that you have drawn judgement on my ability to sustain such an undertaking, as well as the inference for the condition of the coach. If an engine, or transmission or anything else is ever a problem, we have a decision to make. We will make it at that time and not worry ouselves about it until it happens.....do you carry a spare engine????? Your assuming that we returned a few days ago is only that....an assumption. The trip was completed in October. We were never without heat, never have been and doubt we ever will be. There is more than one way to heat a coach. We have that covered. Not sure how in the world we got so far off track here, but I got some very good responses to my request and I appreciate each of them. Most without criticism regarding the post. Meantime, I have not had opportunity to install the new tip and do not know if that solved the problem. Many thanx to those who posted with helpful comments. RCB |
