    I also have a problem with my opener light coming on but the door not raising when I push the button on the wall. The opener doesn't make a sound when I push the button except for a light click. Also, the remote doesn't make the light come on, but it does make the little light on the back flash 5 times. My sensor eyes are green on the inside right, and yellow on the inside left. I think this all started right after a big storm. I have a 2003 Chaimberlain Liftmaster 1/3 horse lifter.

    so far, it is doing exactly what it should. you plug it in and light comes on for 4 minutes. What else did you try. Is wall button lit. Did you push it. What about remote controls. Do they work. Did you code them? Give us something to work with.

The light flashing on the back of the operator 5 times indicates that there is an RPM sensor failure. They can be changed easy enough, but remember to unplug the operator first. The part # is 41C4398A. Your best bet would be to call a garage door company and get them to look at it. Your logic board may also be fried from the storm. Hope this helps.

Need to know how to change break light bulb

Open the truck & remove philips head screw that is located to the left of the tail light housing in the trunk lid weatherstripping housing area. Next unscrew the trunk lining screw to fold back the trunk lining to get at the two plastic wing nuts that hold the light housing.

Unscrew these two wing nuts and slide the housing out, then remove the bulbs and replace. Bulbs come out similarly to how you'd replace the front headlight bulbs (unplug, twist counter-clockwise to unlock and remove old bulb, replace with new bulb and turn clockwise to lock, plug back in).

Solid red typically means bad controller. Try unplugging the furnace, wait about 30 secs, then plug it back in. The possibility that the controller was sending voltage to the valve even when there was no flame is a bad sign. If the controller starts the furnace, watch it very closely and see what it does. If the solid light comes back on, it's time for a new board.

Fridge not cooling

Make sure coils underneath or backside are clean of dirt. Make sure compressor is humming when running. You can tell by moving fridge out and it will be at the back side of the opening on the bottom side of fridge. It will be about the size of a soccer ball. If it has a little of vibration and might be alittle warm to touch. Also open door and make light comes on inside. In newer homes these days they are using ground fault interceptors. Even tho this one is not plugged into one that has the resetable breaker check other walls for one that does have the little red and black push buttons. They sometimes wire some into one ground fault, when that pops, it shuts power to the others. Our house is that way, I have to go to our bathroom and reset it to make the ones in the kitchen work.
