First, it would help if you posted make and model of fridge. Or post what RV you own.
Kinda of hard when you don't post this info.
FR products have different brands and models of residential fridges, 2-way fridges and 3-way fridges.

What bikedan said... plus... has it worked OK previously?
You mentioned flue so I'll assume a LP/Electric fridge?
Were you on LP or electric?
Is your LP supply OK?
Do the stove burners work OK?

Try pulling fuse for fridge ( 12v to control board). Wait a min and replace fuse. Control board may have gone into safe mode for some reason. Make sure your 12V power is OK as well.

Any further on this?

Did you compare the blinking lights to that of the troubleshooting guide in the manual?

Is it a DMR702?

If so, I bet it's the thermofuse. You can bypass it long enough to see if that's the problem.

If it's under warranty you can take it to the dealer and let them fix it or you can buy a new 152ºC thermofuse and replace it yourself.

Here's a thread with pics of the thermofuse and the cutout.

While installing a fan on my Dometic fridge, (viking 17fq) I notice the control circuit board has a 3 amp and a 5 amp tube fuse on it. Does anyone ever check those fuses or had to replace one? Just curious. I bought extras for my supply box when I found them.

I had to replace one of the glass fuses on mine a couple years ago.
Mine blew somewhere along the way when it auto switched from 120v operation to LP (when leaving home) and then back to 120v at arrival. It did work fine on LP. (separate circuitry)

In defense, the glass fuse holder/clips were not tight and were not making good connection on the fuse ends. It got hot, melted the solder inside the fuse and broke the connection internally. Fuse 'looked' fine, didn't pass the meter test.

I have had to change mine when I had the circulation fan was wired to the inside light of fridge. It was hot that weekend and in full sun.

Change the 12 volt wire to the outside 12 volt lug behind fridge and never had a problem again
