The opener will operate correctly sometimes. Then it will quit in the middle of opening or closing: I hear a click and the lights go out. I have a lamp plugged into the same outlet and it stays lit, so I know there is power to the unit. When the unit is stopped on it's own I can tap on the back (near the logic board) and it will come back on. I removed the logic board and reinstalled it and it still does the samething. Then it stops on it's own I can hear the unit hum. After about 20 seconds the unit clicks back on, the humming stops and the light goes back on again. The unit will work sometimes for a day sometimes it quits again after a few tries. Sounds like a bad connection, but where? perhaps the sealed micro switch just above the transformer?

Re: door opener looses power
Motor has a thermal sensor if it gets too hot it trips the sensor till it cools down. Motor may be going bad, or door may have gottin to heavy ( spring loose tension over time) disconnect door from operator. You should be able to raise it easily manually.

Rear Side Door Actuator Control Module
The rear side door actuator control module is capable of on-board diagnostic functions described in On-Board Diagnostic Features . The rear side door actuator control module monitors the door position at all times including during manual operation. After activating the on-board diagnostic modes, loosing battery voltage, or ground to the rear side door actuator control module the Power Sliding Door (PSD) Re-Initialization procedure must be performed in order for the rear side door actuator control module to correctly determine the door position.
Power Sliding Door System Description
The power sliding door system(s) can operate correctly only if the power sliding door is in proper mechanical condition. Any mechanical problems will affect the power sliding door operation and must be repaired before attempting to diagnose the power sliding door system. Manually open and close the power sliding door to determine if the door moves smoothly and without excessive resistance or binding. The power sliding door must also latch and unlatch without the use of excessive force. At any time during power sliding door open or close operation, excessive resistance to the door movement will cause the power sliding door to stop and reverse the direction of travel.
The power sliding door will operate only when the power sliding door on/off switch in the overhead console is in the on position. At anytime during power sliding door operation the on/off switch may be turned to the off position and the system will quit any function in process. The power sliding door will not open unless the transmission shift lever is in the park position and the door is unlocked. When the sliding door security lock is in the locked position the power sliding door will not open from the inside. The power sliding door close function will operate when the vehicle is in gear. The power sliding door module uses the VSS signal to determine if the vehicle is moving during a power sliding door close function. The momentum of the vehicle moving forward adds resistance to the door closing operation. When the rear side door actuator control module determines the vehicle is moving forward while closing the door, current flow through the actuator motor is increased instead of being reversed. The VSS signal circuit is supplied battery positive voltage through a resistor then monitored within the rear side door actuator control module. The VSS signal circuit is then pulsed to ground, or pulled low by the powertrain control module in relation to vehicle speed. The sliding door alarm will sound repeated short tones whenever the power sliding door system is turned on and the door is open while the transmission is out of park.
When the power sliding door system is on and manual operation of the power sliding door is detected the rear side door actuator control module activates the power assist feature. When the power assist is activated the power sliding door will continue to open or close without any further manual effort.
The power sliding doors may be operated using the Remote Keyless Entry System. The keyless entry transmitter will have one OPEN/CLOSE button with a van symbol on it for each power sliding door. The power sliding door ON/OFF switches in the overhead console must be in the ON position in order to operate the power sliding doors using the keyless entry transmitter. When a right hand power sliding door OPEN/CLOSE function is activated using a keyless entry transmitter the exterior lights will flash once indicating the RKE module has received the OPEN/CLOSE command. When activating a left hand power sliding door OPEN/CLOSE function with the keyless entry transmitter the exterior lights will not flash.
On-Board Diagnostic Features
The left and right power sliding door systems operate as independent systems. The on-board diagnostic modes are entered and operate the same in both systems.
The power sliding door systems are capable of the following on-board diagnostic functions:
• Diagnostic Mode 1: An audible signal indicates the diagnostic trouble codes stored by the rear side door actuator control module.
• Diagnostic Mode 2: An audible signal indicates when inputs to the rear side door actuator control module are active.
• Diagnostic Mode 3: Performs an output test of the sliding door unlatch actuator.
Entering On-Board Diagnostics
The on-board diagnostic modes can only be entered in a sequential order from modes 1-3.
• Enter the right power sliding door system on-board diagnostics using the right B-pillar open/close switch and the right on/off switch in the overhead console.
• Enter the left power sliding door system on-board diagnostics using the left B-pillar open/close switch and the left on/off switch in the overhead console.
1. Both power sliding doors must be closed and in the latched position.
2. Place the ignition switch in the OFF position.
3. Place the on/off switch in the overhead console to the OFF position.
4. Press and hold the B-pillar power sliding door open/close switch.
5. While holding the open/close switch, operate the on/off switch through 10 ON and OFF cycles within 10 seconds stopping in the on position.
6. The sliding door alarm will sound 1 long tone indicating diagnostic mode 1 is active.
Diagnostic Mode 1
Upon activating diagnostic mode 1, DTCs will begin to be signaled by the sliding door alarm. The DTCs are 2 digit codes and the codes are represented by the number of buzzes for each digit of the code number. For example a DTC 12 is represented with the following sequence: buzz, pause, buzz, buzz, long pause. Each DTC will be signaled 3 times before proceeding to the next DTC. Refer to Diagnostic Trouble Code (DTC) List . The DTCs will continue to be repeated in this manner until the on-board diagnostics are exited or mode 2 is entered. When exiting the on-board diagnostics all stored DTCs will be erased from the rear side door actuator control module memory.
Sometimes rust will build up on the latch and not allow it to return to the correct position. Try pushing the handle all the way to the closed position and then try your remote lock. Then try to open. The hinge gets build up and does not return all the way. Hope this helps and have a great day.
You may have to inspect the wiring of the devices. If you say the contacts including those for the relay are ok, then the ground connection or exposed conductors may the the source of the problem. Water, vibration may cause failures for such cases.
COULD BE A BROKEN WIRE.
THE POWERHEAD BEING LOOSE MAY HAVE CAUSED ONE TO BREAK THEY ARE VERY SMALL AND BREAK EASILY.
CHECK BY MOVING THE WIRES SLIGHTLY AND SEE IF THE WALL BUTTON LIGHT GOES OFF AND ON.
HOPE THIS HELPS
The 1200 error is caused by a cartridge carrier stall. This can happen if:
The print cartridges are not snapped in correctly.
The encoder strip is out of place.
A foreign object is blocking the cartridge carrier's path.
Try this first step to correct it
Turn off power to the printer and unplug it from the back of the printer.
Insert the power cord back into the printer. You will hear some clicks and motors moving. Pull out the cord again when this happens.
Open the cartridge bay by pulling the face forward and lifting the bay door up. The cartridge carousel most likely will not come to the center.
trying physically pulling the carousel to the middle. (NOT BY THE RIBBON CABLE) If you can not pull it to the middle push it far right as possible. Listen for a click.
After pushing to the right and hearing a click you should then be able to pull the carousel towards the middle easily. Remove the ink cartridges and power up the printer again.
You will receive an error along the lines of black cartridge missing. Open the bay, insert the cartridges, close the bay. if the error still persists Could be a timing belt issue, gearing or a jam, etc. Typically, Dells are Lexmarks...
