Refrigerator problem

I'm having a problem starting a new thread. so I ask my ? here, To the gurus here, can anyone tell me the size of the hole in the orifice, here is why I ask. We went out for 4 nights, once we reached the campsite I noticed the flame on the fridge got smaller and smaller until the flame went out. I took out the orifice cleaned it put it back together, worked great for a while and then the whole thing started over again. I had to do that 3 to 4 times a day just to keep the fridge going. When we got home we searched for an orifice without any luck of coarse. The earliest was 3 to 5 weeks maybe, I said by that time camping season is over in our neck of the woods, so I thought I have nothing to loose by making the hole in the orifice slightly larger, even tho people say don't do that ,it's dangers, it could even blow up, blah, blah, blah. Well as I said I had nothing to loose. So I drilled out the hole with a 0.025" bitt. Put it all back together turned the fridge on and guess what it didn't blow up, the flame was a tiny bit larger. Started the fridge at 1 pm set it on 2 lights, fridge was empty, temp was 23* C in the fridge, by 8 in the morning the temp was 5* C. The other thing I noticed is that the top grill never got as hot as it normally did. By the the way the fridge is a Dometic RM 8501. 

Marwayne, I couldn't find an orifice size for the RM8501 but I did find this generic chart:

I may be having similar issues as Marwayne, regardless who do you recommend as far as purchasing this orifice?  I have unsuccessfully tried to remove mine out of the housing w/o destroying it.  If I were able to purchase a replacement I wouldn't be as timid in getting the old one out.  I have replaced both propane lines from the tank to the orifice.  Regulator may have to be replaced.  Our 177 was purchased January 2011 and has been used a lot.

Hi, I have a surge protector on. It seems like all other outlets work. I will be using it Labor Day and will see if it works on this sites power.
