my blower stays on high even with the key off what causes this

Mine did the same thing. The blower control module is bad. Needs tobe replaced. It is also called the blower resistor. Replaced mine and everything works fine now.

Mine was the same way, I had the same problem, but when I replaced the existing manufactured control module with this one which is very easy to install my problem went away.

yes that is exactly what i had happen just pull the fuse when you park to avoid battery dieing. replaced with this and works like it should again.

This part can cause this too. It also can cause the fan not to come on at all, it just depends. This is a problem with the vehicles that uses it. It is just a bad set up. The new part can also cause the same problem. It all depends on air flow.

jerry my would stay on even with the key off also. sometimes it would eventually go off. it had a mind of its own.put new cm in and all has been well since. not all that hard to replce

Couple of possibilities. 1)check for computer codes. I there I was code that has been computer error attached (I think it is 601) then there Is a fault In computer and the ECM has to be replaced. 2) the heater has its own separate computer an could be sending the wrong signal to the blower or 3) and most likely the resistor has faulted an you have to change the resistor block. This Is cheapest an most likely. Mine has part not col temperature rated so will not work in -40 weather, have to use heating torch to warm up resistor block first.

Had same issue. Replaced control module. If you can locate fuse box and isolate fuse for control module just take out fuse and blower will quit. I replaced module after researching problem online.

I don't know. If it is new it might be a defect. I have 2 of these units and there is a clear difference in the fan from high to low. Mine have been going strong for a year now....one of them was on my boat all winter running 24/7 and still works great. I'd either check with the manufacturer or send it back. Good luck!

If you have automatic controls this is the fix for blower motor not shutting off.

Mine does this sometimes, don't know why, I just put it back up using the "plus" key on the handle

All I can add is that I used my compressor frequently and have not experienced that problem. Contact the manufacturer.

Check your flowmeter the turbine is probably stuck remove it and clean it you should be good

not sure what application your using but mine are all in fireplace inserts and once set to the speed they want they stay on that speed and never turn them off. the on off is controlled by a single pole switch on the wall that turns both gas and blower off at same time, so in my case no off setting is needed anyway

I'm assuming that the blower is not coming on both before and after you replaced the control board. Ensure the jumpers are in the correct configuration and there is power to the board. Test the motor by directly connecting it to 120VAC. If the motor works, the board is installed correctly and it has power then the next thing to check would be the plenum temperature sensor. That is the "enable" for the motor. Does the gas burner come on for a while and then shut off?

Mine came out of the box with one knob higher but it turned out it had just popped off the tuning pot. I pushed it down and it popped back into place and I haven't had any issue since. Hopefully that is all the issue is for your unit.

Other possibility is that the two halves (indoor and outdoor) of the housing are pinching down on the mechanism when the two installation screws are tightened. Mine was like this and I added a thin washer to both the upper and lower screws between the two halves (installation is a little tricky...extra hands help). You can check for this condition by simply loosening the two installation screws to see if the key cylinder frees up.

Hi Patricia...I had the same thing happen to mine but the high pitched noise eventually occurred on all of the speeds. It was not constant...it would come and go but it was very annoying. Couldn't figure out a way to get into the unit to see what was going on. Seemed to me to be some sort of lubrication issue. In any event we really liked the air purifier so we just purchased a new one. It works great and it's one of the least expensive on the market.

Something must be broken or installed incorrectly Michael. I'm guessing a spring may have broken or slipped off. After a year, my highth adjustment still works like the day I first used it. When lifting to the top level (7 I believe), the mower will actually lift up off the ground and I have to steady it with my foot. levels 6-1 are easy to move to though. I would pull the top plastic cover off myself and see if the mechanism has anything that looks wrong with it. You can also contact B&D; directly but I'm sure they don't want an untrained person poking around in there. They will most likely tell you to take it to a service center (May be a good option for you if there is one near by). Something must be broken or installed incorrectly Michael.

What you are describing does not happen with my blow dryer.I suggest you get a hold of where you purchased the dryer from and discuss with them.

I thought I had the same problem but it started going when the heater comes up to temp. It kind of does it's own thing going on then off a minute after the flame goes out. Then the flame comes on and a few minutes later the blower comes on.My basement is big (30 x 40) with 10 foot ceilings insulated and I leave the heat on #3 about an hour before going down to rehearse (musician) and the temp has come up nicely and the blower goes on and off as needed. It also could be a break in period because you will get a slight smell until you put some hours on the unit. One other hint the blower just can't be turned on but the heater must heat up then it will work. I like the unit and works as expected.

I have had this problem also.. could also be why my handle recently came off from the constant up and down. Mine never went down all the wsy just a notch or 2

That problem has not occurred on my heater and I always use it on low setting. As someone else suggested, clean the pilot to get rid of dust.

It is probably the bearings on the fan. You would have to access the motor and oil the bearings.
