Thermador UCV36 - motor won't raise fan

My down draft fan broke last night. My wife pushed the button to stop the fan, upon which it started to retract itself without stopping the fan (correct operation would have been to stop the fan and stay put). I had to switch off the circuit breaker to stop it. After turning the power back on and pushing the button to raise the panel, the motor used to raise it started, but the panel stayed put. After a few tries, I grabbed the panel and managed to simply pull it up (I've never tried that before so I don't know if that is normal) all while the motor (but not the fan) was running. I think the mecanism to raise the panel is two jack screws, but I don't know for sure. Could anyone give me a few trouble shoot hints. Could something in the rasing mecanism have been dislocated, disconnected or similar?

    I have the same problem - the vent is almost fully raised, and the motor turns on, stalled, when the button is pushed, and the fan is not on. It will not go down. Or up.

    My problem is with the 30" Cook 'n' Vent. The unit will raise and operate in all speeds, but when I push the button to retract the unit, it will not retract all the way. It acts like it is stuck about half way down. I am able to push the unit down, but it is very tight, like it is off the track or something.

You have to get the tension off of the hinge and it will drop right in. The spring loaded arm on the door needs to be drawn back until you can (depending on the style) either lock the u-arm into the notch on the other side of the hinge, or put a small bolt through the aligning holes in the side of the hinge. Once you get the arm straightened out a bit and relieve the spring pressure, you should be able to sit it right in there. Be careful though, that spring is strong.

just the switch should be replacable. My vent has a screw at each end (philips flatheads - accessible only when vent is up) just under the top cap. Removing the screws and cap should give you access to the switch. Just make sure you cut your breaker off first.

I would think you can. Most of the cooktops are 240v and the vents are 120v, so the vent may be feeding off of one of the cooktop's hot wires. My vent is fed from it's own receptacle but is harnessed along with the cooktop's 240v.

Wife has a mp826 4g last night at work she said it got hot and stopped working i charged it and used thereset and still does not work! ?????

It's likely that the hardware got fried from overworking itself and has shut down to protect itself. Wait a day to see if it will work again. If not,then the hardware is damaged and you will unfortunately have have to find a store to repair it or buy another one or get a different one.

Hope this helps : )

Broan model 2736A won't stay up

In my case, I pushed the button, the housing goes fully up, then right back down. I removed and disassembled the unit for cleaning. After Assembly I located two microswitches that cause the extension moror to stop at the top and at the bottom of the swing. In my case, the inertia of the motor caused the unit to "Coast" thru the top of the stroke and continue back down. I bent the outer 1/3 of the metal tabs that depress the microswitches so that the unit stopped rising a wisker sooner and no longer goes back down without pushing the button. The same coasting theroy may apply at the bottom of the stroke. The motor that runs the up and down motion is controlled by three switches, the two limit switces plus the momentary push button switch. If you don;t need to completely remove your unit for cleaning, the microswitchs can be located by removing the fan housing and looking up from inside the cabinet (under the stove) on the right side. IN my case, there was 10 years of goop to be removed.

The radio antenna on the Volvo S 40 is fully retractable. It opens up upon swtching on the radio and retracts upon its closing. The radio antenna is now stuck although the motor can be heard.

I have similar problem. Not sure why it started, but the motor TRIES to move the antenna when turned on or off, but it pushes it maybe an inch or two then stops. If i try and pull it up or push it down it is VERY hard to do, feels like i am forcing it somewhat.
Its almost like the motor has forgotten where the top & bottom is. Any solution would be much much appreciated!

Will not start up

If it's not beeping during the first start up then it's not POSTing.  Beep means everything connected to it seems to be functional ie PnP  
Try pulling out your memory and reseating it.   Try pulling out your battery for 5 minutes then plug in ac(without batt) and see if it will boot.  Try pulling your hard drive and reseat.  (access by covers on bottom...dont be scared. Touch something that's grounded just before you remove) If all this and still no full POST(with beep/s) then sounds like a new mobo or processor.

The little button on the main circuit board may be sticking intermittently causing your set to do this. This little push button was operated by the piece your 3-year old broke off.
