dougrainer wrote:The check Lite is a function of LP gas ONLY. It just says that at sometime, the refer needed to light on LP and did not. Once that happens the check light comes on. You stated your LP was OFF. At some time, the 120 AC to the refer probably stopped or the line voltage went below 104 volts and the refer tried to light on LP. Since your LP was OFF, it could not light and gave the Check light. Leave the LP ON, so if this happens again the refer will light and then go back to 120 when the 120 problem goes away. Doug
Yes, that's a good plan. What has me bumfuzzled is that when we run the reefer on gas, the check light (before lighting actually occurs) comes on and stays on (until lighting happens.) In this case, the light was flashing.

Our "check" light kept coming on last saturday. We were running on propane. both tanks filled on friday. It worked fine friday and sunday, but not Saturday. It would stay lit for about 5 mins then go out and check light would be on. The waterheater and stove worked good. I don't get it, any ideas? Thanks, Chris

Very interesting! DW used the curling iron (or dryer, can't remember) earlier that day. I'll check that! Thanks!

How old is it? Is it a Dometic? Have the control board tested. Had the same problem, replaced with Dinosaur board, no issues since.

Sorry, I did not catch that you said it was FLASHING. I have never seen one flash. I would suspect the control board. Or course it can only be one of three things (1. The control board 2. The eyebrow board, or 3. The control harness). Does it always flash? Or has the flash gone away now? 2006, you may still be under the 3 year warranty (3rd year part only). Doug

The trailer is 70 miles away in storage, so I won't be able to check any of this out for a week or so. I surely appreciate the input.
Thanks,
Dave

On a Dometic, if it's not reasonably level, the gas flame will shut down and the "Check" light will come on if there's no other power available.

ABSOLUTELY FALSE. Nothing in a Dometic refer will shut it down on LP or 120 volt if unlevel. Doug

If my Dometic is operating on LP gas and is more than about a "half bubble" off center, the fridge will quit cooling and the "Check" light comes on. On 120 volts, it's less strict about being level.
I don't know of anything else that would cause it to shut down. It has always operated perfectly when level. The only other time the "Check" light comes on is when the fridge is turned on but there is no 120 or LP gas. I'm open to any other explanations.
Maybe it's not "ABSOLUTELY FALSE" for all Dometic fridges.

I am a Master Cerified RV Technician and Dometic and Norcold trained. I stand by my statement. NO Dometic has any control or sensor that will stop LP or Electric and throw a Check Light if off level. The ONLY thing that will cause the check light on a correctly operating Dometic is if the LP does not light or stay lite when it is supposed to be operating on LP. There is NO level control or any control that a Dometic has to know if it is operating off level. Some NORCOLDs do, but not Dometic. The Norcolds do not have any type level control, BUT when operating out of minimum level requirements, the Norcolds have a control that realizes when the refer is not cooling down and starts to raise the temp because "something" has caused the refer to not cool down correctly (Too off Level) and then throws that famous NO CO code and shuts down the refer. If yours shuts down from 1/2 bubble, you have another problem. Took awhile but I found your year model (1992) For your INFO, your year model Dometic (1991 thru 1997) had a KNOWN problem with the Control boards that caused Intermittant Check lite. The fix is to install a updated Control with a Ground Harness kit. Take the black cover off of the control board. If the epoxy is NOT green but beige, you have a defective control board. Install an updated (current) control board with a Ground Harness kit. About $125 retail total for both. Doug
