Door want work work with wall switch and no light on wall switch

The door worked fine till the power went off the whole house with the door in the open position. I left with the power still off and the door still in the open position. I unlatched the door from the closer so i could close the door mannuly. when I came back the power was back on and the closer had run down and did not completely latch with the door. the door and closer seemed to be in a bind and after working with it a minute it latched. now the wall switches want open the door and the light in the switches want burn. the big light on the opener does burn. we do not have any remote opener for the door. It worked fine till the power went off. thanks for any sugestion.

Make sure the wires from the wall button are still connected to the opener and are tight. There are two and they should go to terminals 1 and 2. You can take a screwdriver and momentarily short between those two terminals and the opener should run. If it runs with the screwdriver and not the button it is either the button or the wiring. Try releasing the door from the opener and see if the opener will run this way. It may still be in a bind.

Just quit. Worked fine one day. Next day went to turn it on and nothing happened. Fan is little over a year old.


Control switch, circuit breaker, or loose wire are main suspect.
Rarely does a motor just stop working.

Check circuit breaker.
Open control switch and test for power and check for loose connections.
Install ordinary on-off switch and see if function resumes.
Check wire connections at fan.

Hi, Working with a Sears 1/2 HP garage door opener that can be activated by a wall button or remotes. No key pad. About a year ago, I replaced the old motor, since it only turned in one direction. I...


The opener will not work without the sensors. Make sure you don't have a broken wire going to the sensors. Make sure the small light on each sensor is lit and not flickering. If you cannot get both lights to come on you have either a bad sensor or a wiring problem. If the main light flashes 10 times it is definitely a door sensor problem. The wall control may be bad now from usage. Remove it from the wall and short across the 2 wires. If that causes the door to try to move you then know the button is bad. You can also short across terminals #1 and #2. That would eliminate bad wiring to the wall control. Make sure the connections on the back of the motor unit are tight and that the 2 white wires from the sensors go to terminal #2 and the white wires with black stripes go to terminal #3.

I installed a dimmer switch it worked for a few days


your not doing anything wrong...some lights that have voltage reducers in them,such as cieling fans, cannot be fitted with dimmer switches, the voltage reducer,or transformer as they are sometimes known,inhibits the full flow of power....you have to get a dimmer pack suitable for working with transformer induced lights

No power to dishwasher


Do the following:
  1. Check the power from the wall outlet or the branch circuit itself.
  2. Check for a blown fuse or a tripped circuit breaker.
  3. Check the wiring connections of the dishwasher from the house wiring.
  4. Check the door switch. Remove the control panel cover or the interior liner of the door whenever it is applicable. Replace if defective.
  5. Check the timer or selector switch. replace if defective.

Kenmore dryer does not turon on


CHECK THE FOLLOWING---


1. No power to the dryer
Make sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in.

2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the door switch if found defective.

Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.

Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.

3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

4. Timer/control
Replace if defective (note: uncommon problem).

Check inside wiring by the driver's side door hinge. Remove the rubber boot and you will find broken wires. Make a splice and you are fixed!
