i bought a 1986 class c motor home about 6 weeks ago or so and i have now been on two trips in it. this past weekend i went wheeling up in clayton oklahoma and stayed the weekend and everything was great and the refridgerator worked perfectly. i came home sunday and unpacked and turned the fridge off and opened the doors so condensation would not build up in it. well yesterday i went to go put some stuff back in the MH and when i opened the door i can smell the amonia from the fridge. is it toast or is it possible thay it can be fixed? i had someone tell me one time that when this happens the fridge will have to be replaced so i am basically just checking to see if this is true. thanks
