There is a good chance the inside blower fan in your Coleman Mach 8 AC will blow apart. “No pun intended”. It could be 6 years old or 2 months old, these are just a poorly made part of the AC and it will go “BAM” at some point. It is plastic after all that is spinning up and down at a high rate of speed.
So this will be a quick blog post, as the video is what you will really need at some point, that and the fact that the actual part can be very hard to find! Really, they are such an IN DEMAND item that I now carry a spare as they can be that hard to find!
Which is why right after one of ours blew apart I needed to make a video, and send this quick PSA, so that you know that… 1) You can fix it yourself, and 2) Hummmm….Keep one in stock as you do not want to be in 90+ weather, lose the fan, and then find out NO ONE HAS ANY.
First stop was Amazon… Out of Stock. Then two online RV Parts sites cancelled our orders, a day later after the order was placed, stating…”We are sorry, it seems we are out of stock.” even though they still showed on the site they were in stock. AUGH!!! So after 3 waisted days of just trying to get the part, I ended up buying it from the Tiffin Parts Store directly (Though at a higher cost and paying really bad shipping prices.) Took 4 more days to come in. So it took about 8 days to get the part so good thing it was not 90+ out!
So I was lucky and went back to Amazon the next morning and they showed the Coleman 1472A1191 part in stock again, so I ordered two more. Good thing because by that evening, as I went to get a link for my friend, they already showed “Out of Stock” again.
So…Here is the link to the Coleman 1472A1191 part on Amazon: https://amzn.to/32ghbmW
If they have any, get one as a standby. If they do not, check back daily as they come and go SO FAST. Then when the time comes, remember this video to help you fit it yourself.
Here is another general link to a Google search for the part incase Amazon does not have any…but if they don’t it is not likely anyone else will… https://g.co/kgs/qEmFok
All in all…Hope this may help you “keep cool” when the time comes.
I had this happen back I Mesa Az. LaMesa came out right a way and fix it under tiffin warranty. All good now.
Chewing gum is a great tool to handle small items at the end of a nut driver.
Also, we had an AC go bad and the entire unit needed to be replaced. We had trouble sourcing it and wound up buying it from Tiffin. It was cheaper, including the freight.
Nice Tip on the gum. :)
Good video. I believe you have a 2015 coach where the A/Cs are not controlled by the Spyder system. Same with my 2016 bus.
So, how do you control your A/Cs with your phone?
Hi…We installed smart thermostats… Video: https://youtu.be/oytfW49QuyQ Post: https://turtleherding.com/2019/09/mod-smart-thermostats-in-a-rv-yes/
Great video! Working on an RV always looks a lot harder than it is. Usually, the issue is getting to the part you need to replace and knowing what part you need. Just something to think about – is there any PM that can be done on the AC while you have the cover off? Coil cleaning, checking the condensation drain, etc.
You surely can clean the outside coils when you have it apart. (After you take off the first cover) I would not recommend doing the inside coils with a hose as then water would get into the ducts. :)
Thanks for the tip. I was able to order one at Amazon
I am waiting to see them show up as Out of Stock…so glad you got one! :)
Sounds like a business opportunity for a jobber to make some out of sheet metal and sell them.
I’m a retired machine maintenance tech for a large defense contractor. We were trained, as part of our safety classes, to confirm that all energy sources (electric, Air, hydraulic, etc) were off right at the machine before replacing parts. There were times where I found voltage I wasn’t aware of even though I was sure the machine was properly locked out.
Thanks for a great video as always.
Yes, cutting shore power as well as having the AC’s in the OFF position would not be a bad idea to be really safe! :)
Hi David and Brenda,
Yep, you will need one. We did. My husband was able to repair the fan enough to make it limp along until we could get one, so now we have two spares – a new one and the limp-along.
Yep, you will definitely need one.
1. Did you clean fan blades in the past?
2. Did you ever consider replacing the brown shroud with a white cover?
Hi…No, we keep our intake vent filter clean as we can. Opening it and removing the fan just to clean it I did not see the point. Not that the build up you had seen was after 6 years. Again, we clean our intakes at least once a month…if needed. As far as replacing the black shroud with white…No…I would not see any point in doing that. IF you are think heat from sun…Non issue based on the venteting and that is it moving air through the system when running. Otherwise, there really is nothing that a white cover will do for you vs a black one. (IMHO)
I have had to replaced 4 blower fan in the last 2 years. Has anybody done a comparison on the the Ac’s with white cover and black covers to see if possibly the black ones are breaking more often then the white cover. Black more heat retention. Mine are black.
Hi…I would have to think that this makes no difference as the fan is inside a black, think, housing. Thus I personally would not think the cover would make a difference in this case. (IMHO)
