Purchased 2006. Ceiling mounted. Just stared overheating after approx 10 minutes after last bulb replacement in March of 2010. Floor fan pointed at projector helps. Tried cleaning. Running right side up makes no difference. Wondering if it could be a bad lamp (runs too hot?).

    I also had set the 'high altitude' on so that the fan runs on high all the time. Still needs the floor fan. The internal fan does appear to be working as I can hear it.

    Nope. Tried Optoma certified lamp w/cage. Still overheats without external fan and high altitude setting. I changed my mind about paying for a solution, too many horror stories in cyberspace about this. I'm very techncally adept and have tried all obvious options.

Yes, if bulb was low price and was installed in old lamp casing then it is bulb that is not good and creating too much heat that exhaust fan can't throw out to make projector cool enough so temp sensor activates and send over heat signal to system control chip thus projector shuts down.
Please install original lamp that comes with casing to solve this issue.
If lamp was original then check exhaust fan that might be running slowly due to stiffness in bearing so temp sensor finds over temp in projector.
Hope these info will help you.
Thanks.

Hampton Bay Mercer ceiling fan keeps buring out bulbs
Halogen bulbs are a lot hotter than other bulbs and have a much shorter life span. It is the nature of the bulb. You can see about changing just the lighting fixture on the fan or look into getting an LED bulb, they run very cool compared to halogen and last forever.

Floor model of a ceiling fan ... think about that for a minute!

I have to say no, you cannot do this. It may be possible but not without a lot of pain and extra expense. I have installed hundreds of fans. You may possibly be able to shorten the pipe that holds the fan but to actually mount it to the ceiling? You will have to have the ceiling hardware to do this. There goes the price benefit even if you can find the proper adapter/ceiling hardware.

Try shortening the pipe that suspends. You may find joy there.

Thanks for your question today. And thanks for the smile ... floor model ceiling fan :-)

They actually have bulbs that are just made for ceiling fans, but can also be used for other things as well. You can get these bulbs at Home Depot, Lowes, etc. You might bring the bulbs with you if possible as sometimes it can get confusing after looking at twenty different designs. Hope this helps.

Bulbs burning out in Hampton Bay ceiling fan
I would suggest getting an electrician to check the current running through the wiring. I had installed a similar fan in my grandmother's house a couple of years ago and had the same problem. After a couple of months of constantly changing bulbs, I brought in an electrician to check the current and found that there was a short in the wire which kept causing just enough of a current surge to blow the bulbs.

NO POWER TO UNIT...
yes. it's warm up there. and it's suceptible to alot of dust and dirt. all of that will cause the projector to overheat frequently. also: if you've had to reset it that many times, it's wearing out, and you should replace the bimetal breaker (the little red button).

Ceiling fan
If the fan blade mounts are removable, go to your local hardware store with one of the mounts, and find some screws that will fit. You might not be able to get the same color, but if you check a few stores you should find something with the right shape of head to fit snugly.

Projector overheating and turns off after 20 mins
I have a HP VP6111 projector that works fine on a table top but overheats ( overheating ) when turned upside down and hung from my ceiling. My solution...I went to Circuit City and bought two 80mm computer fans. I also purchased a 12V power supply from Radio Shack. I put one fan on front of my projector and the other on the back of the projector and wired them into the 12V power supply. I mounted both fans with velcro. The front fan pushes air and the rear fan pulls air. The projector now runs fine without shutting off. The fans are 12V and push 34 cubic feet per minute of air. I am very happy with this solution.
