We need assistance with our RV Magic Chef 3 burner propane gas range with oven. We think the part number is 8114P 470-60 taken from the inside of the oven. We need the owners manual to figure out what part needs replacing inside the oven - it has to do with the incoming gas line. Correct return email is nana-karen@verizon.net. Thank you. This is a second request. We never received an answer to our inquiry last week.
