You may have a fairly cheap problem that can be found by nearly any electronic tech in possession of a couple of instruments; specifically a decent multimeter and maybe a capacitance meter.
It is apparent that either some passive component or low-level transistor in the timing/sensing circuit has bit the dust.

My craftman garage opener will not close. The up arrow blinks 3 times and the down arrow blinks 2 times. the button on the unit will not open or close it. It will move about a foot then reverse back.


try holding in the wall button the whole time. if the door closes, then you have an issue with the sensor wiring. if the wall button closes the door while holding in, then post a comment below and we will tell you next steps.

Hello Jennifer

Here is my step by step instructions to follow.

1. Look inside your refrigerator and locate the temperature control switch. This is usually situated around the middle of the refrigerator's back panel. Some switches have a wheel mechanism, whereas others use digital displays.
2. Turn the temperature control wheel down to zero or switch to "Off" if you have a digital display.
3. Move your refrigerator away from the wall. Refrigerators are extremely heavy, so enlist the help of another person, if possible.
4. Unplug the refrigerator cord from the wall outlet. Leave unplugged for around two or three minutes.
5. Attach the power supply back to the wall outlet and position the refrigerator back against the wall. Your refrigerator temperature is now reset. Switch the temperature control back to "On" and adjust the temperature to the level required.
6. Open the ice making area of your refrigerator if it is producing watery ice cubes or an inconsistent water supply.
7. Locate the water filter status light inside the ice maker. This is usually a small rectangular light situated at the side of the ice maker.
8. Push the switch next to the status light seven or eight times in quick succession. This will reset your ice maker.
9. Check the status light. This should turn from red to green once the switch has been pressed several times. The green color indicates the ice maker has been reset.
Remember if you FRIDGE is on warranty you just send it first to the manufacturer.

Best Regards

E3 error on LIfesmart heater


Even after replacing thermostat and motherboard offered from company, my heater would trigger e3 error code and shut off. After several (maybe 100!) different attempts to plug in and operate, here is what worked for me!
Depress the power button on the heater while plugging in to wall circuit. Continuously depress power button. It will run through a test cycle and attempt to start. Keep depressing the power button as the heater tries to start, then shuts down with e3 error. While the power button is still depressed, unplug the unit from the wall. When I plug back in the wall the E3 error is gone. Good luck

2003 Explorer A/c did not appear to be blowing very hard (but was cold). Adjusted verticle vent knob and had a very loud thunking noise. Returned everything back to original position, ac seemed to work...


It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch, and/or a faulty Blend Door Actuator. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.

I have a craftsman opener. I will go up and down 10-15 times with no problem and then it will go a foot or two (up or down and stop. (wall control button light flutters). this will happen several times...


The fluttering wall control light makes me think you have a loose connection. Pull the logic board and check for loose connections on the printed circuit.As intermittent as it is it will probably be very hard to spot.

Wall button stoppd working.


If the wall button is locked it will only prevent the remotes from working. They do go bad. Try removing it from the wall and short the 2 wires on the back together momentarily. If the door moves you will know the button is bad. If not try momentarily shorting terminals 1 and 2 together on the back of the motor unit. Maybe the wiring to the wall control is bad. It won't shock you so you don't have to worry about that.

The door reverses back to open position instead of closing


SOUNDS LIKE A SENSITIVITY ISSUE UNHOOK THE DOOR AND TRY IT MANUALLY TO BE SURE IT DOESN'T BIND OR IS TOO HARD TO OPEN OR CLOSE.

IF ALL IS WELL CHECK THE SENSITIVITY SETTINGS ON THE BACK OR SIDE OF THE OPENER.

YOU WANT THIS SET AS LOW AS POSSIBLE AND STILL OPERATE THE DOOR WITHOUT REVERSING.

NOTE: THE FULL RANGE OF ADJUSTMENT IS ONLY ABOUT 3/4 TURN SO MAKE A VERY SLIGHT ADJUSTMENT AND THEN TRY IT AGAIN.

HOPE THIS HELPS

Remote does not open or close garage door; inside button flashes


What has happened is that you electric eyes are blocked or have gone out. The eyes are at the garage door about a foot of the ground on both sides. There should be a red or green light on one of them. If not some thing is blocking the beam that goes across the door. It is a safety beam so kids can nt get hurt when the door is coming down. If the beam is broke the door will go back up.
