Any of you folks know if the two wire overheat fuse (screws into the top of the unit) can be "upgraded/adapted" by the reseting thermal type fuse? Thanx much!  RCB | ||

That fuse shouldn't normally let go. It usually requires a "lack of maintenance" condition to create the overheat conditions in which to blow. Resettable would allow a continued abuse without the cause being corrected. Probably not the best for a busnut? happy coaching! buswarrior | ||

BW...I accept your premise...and your humor! ....however. It is not a "lack of maintenance" thing. It a lack of desire to pay $30 plus to replace the fuse when system is full of air....while doing maintenance,,,,in other words, bleeding the air from a Pancake setup often leaves lots of air in the system, and when an air bubble is in the line, it is often difficult, almost impossible to detect. And, that is what blows those expensive fuses. Each year I spend "hours" working out the bugs, but seem to get it "wrong" from time to time. It is not something I look forward to, believe me. The unit itself is in the lowest place in the coach. I am open to suggestions........(helpful, please) I ask again...is there an "upgrade" for a 2010? RCB | ||

Yes, I have blown several overheat fuses in my Webasto and now have an overheat sending unit on the hot outlet side of the Webasto that does not need replacing everytime I get an airlock and overheat the unit. I have replaced that &*^! overheat fuse at least 4-5 times. Usually it is because of air in the system but once it was because the connector for the water circulation pump fell off. I won't go into details of how my Webasto is set up and why I get airlocks but I have learned to pull the cover off the Webasto before I fire it, and feel the inlet and outlet hoses to make sure the water is circulating for 5-10 minutes. If the outlet hose starts getting real hot I know I have air in the system and immediately shut off the Webasto before the overheat fuse (before my upgrade) blows. So anyway, I used an overheat shutdown sensor off an Ingersol-Rand air compressor (with diesel engine) that is normally closed to 210F. I used to work on IR equipment so I just happened to have one. If you would like you could call me at 928 771 0045 and I could give you the whole story over the phone. Geoff General Diesel Service, Prescott, AZ | ||

My apologies, my post should have been prefixed with "In a bus fleet environment". I had not considered the airlock opportunities that our various busnut accessories introduce. Thanks! happy coaching! buswarrior | ||

Yes, there is a resettable overheat fuse for the DBW-2010, and we have this type fitted. I'm sorry I don't have a part number, but if you contact Sure Marine in Seattle they can get it for you. We had the same issue, blowing the original expendable type when we were first trying to bleed the system, and Sure recommended the resettable replacement. It resets with a little button and you need to take the plastic shroud off the thermostat opening in order to do it, but still way more convenient and less expensive than replacing them. -Sean http://OurOdyssey.BlogSpot.com | ||

Geoff...I'm "on the road". Any direct part # you could furnish? Sean...Sure has done work for me; they were reasonable and informative. Guess I'll give them a try... Expand a bit on "first trying to bleed the system"...and thanx for the input!!! ...as usual! RCB |
