Dometic fridge check blink pattern?

My neighbor has a Dometic RM 2682 that's pretty much like ours. The fridge seems to be working just fine but the check light is blinking in a very specific sequence. I've posted a video of it below with beeps added to the soundtrack to make the pattern easier to understand.

I've seen the check light on my own fridge light up when there was a problem with the propane but I've never seen this before. The Dometic manual I have doesn't mention flash patterns.

Did you mean RM2862 (No RM2682 model

'Check' Light does NOT Blink to signal an error code
'Check' Light comes on when Flame fails to light & prove it lit

'Check' light blinking like that indicates:
*Bad wire connection on Upper Display Board
*Bad wire connection on Lower Circuit Board
*Bad Circuit Board
*Thermocouple connection OR Spark Electrode if no thermocouple (Depending on Model Production Year)
*Flame sputtering On/Off due to obstruction in orifice/burner

I would start with flame....have someone watch it while 'check' light is blinking
Good steady flame...then could be ANY of the other reasons
Next would be to check the thermocouple connections
See Pg 20 Section 7.3 to test thermocouple

See Pg 13 for Upper Display Testing
See Pg 17 for Lower Board testing
