Unless your door is stuck in the open position you have a bad logic board.

Pop open the cover and check for loose wiring. Also check to see if the capacitor is still good that powers the motor.

SOURCE: Garage door opened, won't close

If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.

SOURCE: Craftsman garage door opener - Clicking/blinking - no open/close

First, check the safety eyes. There should be a light on each eye that is on. If not, realign the eyes. If that does not work, check the force settings. They are the blue adjustment screws. They should be set on 4-5. Do not go above 6 or there is a problem with either the door or opener, or both. If this does not work check all of the wiring on the back of the opener. 1 should be a red wire, 2 should be three white wires and 3 should be two black wires. Check the wiring to the wall button. the back of the button indicates red and white screws. To take off the wall button you will have to remove the big white button if you have the "deluxe wall control" If this does not fix it, respond with more info on door position and what happens with remotes and wall button.

Frigidiare lffh21f7hwa freezer When door is opened light will flash on and off you can hear a clicking sound, every so often it will have to be reset by unplugging

You are talking about the inside light right? The clicking is coming from the controls panel right? I think the problem is related to the control board itself because there is a relay that switches the light on when the door is opened part number=> 297366300 Frigidaire Freezer Main Control Board Otherwise if removing the bulb will stop the problem, please try that.

Garage door opened fine but now when I try to close it, all I hear is a buzzing sound for 3 sec., light comes on but door won't go down.

Your trolley may be jammed against the bolt just in front of the motor unit. If so, loosen the chain enough to relieve the strain on the chain and then run the opener until the door is closed. While the door is closed locate the 'up limit' control on the side of the motor unit. Turn this control 2 full turns in the opposite direction of the arrow printed on the cover. Tighten the chain.

When i open the door only the light is supposed to come on. the light comes on but the fan and turntable run also.

This is a very hazardous condition. DO NOT stick you hand inside the unit as you may well get yourself burnd by microwave radiation. It appears that there is either a problem in your control panel assy or that you have time on your timer and the unit has a defective door switch allowing the magnetron to keep running with the door open. There are at least 3 protective micro-switches in the door closed and latched circuit. Very slowly depress your door open button or pull the door open slowly (depending on unit type) and listen for 3 distinct switch clicks. All 3 click should happen in less than one one half inch of the door opening. Try is sevral times and listen for the 3 clicks repeatedly. If you do not hear 3 clciks then you have a bad micro-switch If you hear all 3 clicks, more than likely your controll panel has a failed relay on it.

Liftmaster pro 1/2 hp wont shut in one button press

You have a door sensor problem. Either your main light bulb is burned out or you don't have one in your opener. The clicking sound you hear is the relay for the light. Both of the door sensors should have a small light that is lit. Tweak them until they are.
