Error code "04"( won't light)

If the light has gone out than whatever problem the engine computer detected has resolved itself. Eventually, if the problem does not come back, the codes will erase themselves. Otherwise a scan tool will be needed to clear the codes.

The Dometic RM 2820 was working last night. This morning it was not cooling and now the front panel and interior light are not working. No smell of ammonia. Any help with this challenge? Thanks,

Either its a bad new battery or tour altenator isn't charging it. Jumpstart it.

It is flashing a code need to take to a shop and have them put on computer to find out code and replace part.

Hi, It almost sounds like the battery won't hold a charge anymore which means you need a new battery. Since the camera isn't quite a year old yet I'd suggest contacting Nikon and seeing if they'll do anything for you before you buy a new battery.

There are sensors just underneath that may be covered in excess toner waste. I tend to see that a lot when the company i worked for did canon machines.

You probably need a new printer.

I had the same issue a few years back but with actual symptoms of malfunctioning. I had mine fixed under warranty. The service tech told me it was a faulty circuit board. Works perfect now. I think the warranty is only for the first year to cover labor and parts. Not sure how much it would be out-of-pocket. This happened within 3 months of a brand new purchase. Hope this answered your question.

How many miles on the plugs and wires? Misfire can be caused by either plugs or wires, after that check the injector for that cylinder. Let me know what u find. Curt

I will need the model number of your set in order to help you, but different models have different meanings for the error code. Your set is flashing an error code. Please respond to this and I will be able to help you with the problem.
