Dryer will not run. Repair company states control board is bad. $ 290 to replace. Note I ran the Console diagnostic test and all the touch pad buttons are normal.
One thing does seem odd, though the dryer will not run. When I attemt to start, the check lint led flashes each start attempt. Led turns off when the dryer door is opened. Lint screen is clean, inspected the vent exhaust plenum and the duct for blockage.
If board need to be replaced. Does not seem complicated. Any issues if it is replaced with out othe testing or meters to check.
Priced the board online, seems that pn 3978696 it has been replaced. Price about $ 170.

Kenmore Elite Dryer HE4 Quietpak 9 Model 110.85091400 has 4 dim lights showing on the console display but won't start or respond
Our dryer just quit working yesterday and I am puzzled. There are four lights very dimly lit on the display. They are the Casual button, the Timed Dry button and two of the segments in the oval time window. I have found the information online about how to test with a multimeter to try and figure out which board is bad. Unfortunately all these instructions require you to have the dryer in the diagnostic mode by pressing the More Time/Less Time/More Time/Less Time in less than 5 seconds. When we do this it does nothing and will not enter the diagnostic mode. When I am testing with the multimeter on the P3/P4 connections I am not getting any readings of voltage at all. Is this because of not being able to get into the diagnostic mode? Should I still be getting readings? I know we have power to the dryer because the light still turns on when you open the door. The cost of buying both the main control board and the front console are prohibitive for us and I would like to only buy the one that is bad. I have also tried the testing with the multimeter on the front console buttons and also get no readings of ohms at all. We have a very busy household with lots of kids and this dryer is very essential to us so the quicker we can get this fixed the better. Thank you in advance for your help.

From the techincal document found in the dryer bottom panel
TEST #4a Dryness Level Adjust
NOTE: If the customer is complaining about the clothes being damp and the moisture sensor passes TEST #4 "Moisture Sensor Test- step 3, then the total dry time can be lengthened by changing from a "Lo" for short auto cycle to "Hi" for longer auto cycle.
1. Activate the Diagnostic Test Mode. Press the following button sequence: MORE TIME ~ LESS TIME -+ MORE TIME --+ LESS TIME - all within 5 seconds
1. In diagnostic test mode, press and hold the Auto Dry Level key for 5 seconds. The dryer will beep and the current auto cycle mode will be seen on the display. The factory default setting is "Lo".
1. To select a different auto cycle mode, press the Auto Dry Level key again. The dryer display will flash and show either "Hi" or "Lo"
1. With the display flashing the selected auto cycle mode press the Start key to save the setting and exit diagnostics (the Start key in this mode does not start a drying cycle). The result will be stored in EEPROM of the control board.
SO EASY JUST TOOK ME 3 YEARS TO FIND IT
Bad control panel. Replace the control panel at repairclinic.com. When your control panel clicks like that it means that a resistor or solder joint has gone bad and it is cheaper and easier to just replace the board
