14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

Jun 27, 2006 - Now, I cannot get the light in the sensor at the door to come on. ... the green LED went OUT about 1/2 way up the door opening sequence. .... other is working (I don't recall if it's green or amber, but know that it is lit.) ... Their is also a green LEDflashing 2 times every 5 seconds or so at control center of unit.
If the main light flashes 10 times when the door reverses it is a door sensor problem. Make sure the sensors are pointed at one another and the small light on each sensor is lit and not flickering. If you cannot get both lights on you have bad sensors.
If when you try to close the door the main light flashes 10 times and the door reverses to the open position you have a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. If you cannot get both lights to come on you have a bad sensor.
The code you are seeing with 5 blinks is "RPM sensor or motor overload." We can eliminate the motor overload because the door is trying to close. The RPM sensor is a small printed circuit board just in front of the motor. It's a snap to replace and is available at any good door opener company. They will know exactly what you are talking about if you ask for an RPM sensor board.
