My crown CE 1000 fan keeps getting stuck; it will work fine, then it will go to start up and will just sit and buzz, unless I give it a little push (I took off the plastic grill). Is this a simple fix, or does it need replaced? And if so can I do this myself?

It sounds like there might be a dead spot on the fan windings. The fan part number is 133551-1 and can be purchased from the Crown parts department at 1-800-342-6939

I had a similar problem with my XLS - there is a sticker holding the fan blade over the axel(?) - it broke down at a gig so the quick fix was to glue a hard piece of plastic in place of the the sticker that came loose.

Is this typical to use a sticker?  If so for this model, any plans to improve the fan construction?

Other than that I have to say its a great amp!

I have a technical question now. I called crown parts, and the fan is $50 or something. Since I can buy the same -exact- model number fan at a local parts distributor for NMB (the manufacturer of the fan) I would like to do that. It is only $17. My question is can I cut the plug off my old fan and resolder it to the new one that just has two bare wires? Will this work the same as the crown-made fan?

One question, how old is the CE? If it is less than 3 years old, it would be covered by the 3 year warranty. Also the XLS would be covered. smile.gif

I don't think it is - I've had it for 2 years and I got it o Ebay ;-) So anyway, this would be the same fan, right?

You need to make sure the amperage rating of the new fan is not greater than the fan you are replacing or this can cause the internal fan circuit to overheat and fail.

thanks for the tip. I was able to purchase the NMB 4715KL-05w-b40 fans (that's the oem part) on ebay - I had to buy 3, but they cost a total of $17 shipped, all brand new, and all I did was cut the connector off the old one. They work great. If anybody needs a fan give me a holler... :-)

Well, strange thing, the new fan got stuck today. I unjammed it with a butter knife and it's fine, but why did that happen?

Well, I'm having this problem again, but now the fan has stopped completely, and despite any help it wont start again. I've tested the fan and it's fine, starts every time from a 12v power supply. When the amp gets warm (just sitting on the bench, a situation where the fan would normally kick on for 30 seconds or so) the fan output tests only half a volt, so it looks like the problem is with the fan output. What now?
