How to Adjust an Orifice on a Maytag MGR5870?

When you convert a Maytag MGR5870 gas range from natural gas to propane, you must change the orifice on each burner and inside the oven. The orifice is not adjustable, so if you switch from one type of gas to another, you must change them. While the procedure for converting a gas range is the same for most brands, you generally cannot use an orifice from one brand of gas stove on another, so you must be sure to purchase an orifice kit specifically for the Maytag MGR5870 before you begin this project.

Things You'll Need

• Adjustable wrench
• 1/4-inch drive socket set

Instructions

1. Pull the stove Maytag stove away from the wall. Turn off the gas supply valve if the stove is connected. Disconnect the gas line from the stove using an adjustable wrench if it is connected.

2. Remove the steel grids from the burner areas on top of the stove. Lift the top of the stove up and prop it in place with the prop rod.

3. Remove the orifice from each burner assembly using a 1/4-inch drive socket and ratchet. Place the new orifice on each burner and tighten it with the socket and ratchet. Do not over-tighten the orifice or you will damage it.

4. Remove the cap from the pressure regulator under the stove using an adjustable wrench. Remove the copper insert inside the regulator and flip it over. Put the cap back on the regulator and tighten it with the adjustable wrench.

5. Tighten the orifice on the oven burner assembly using a socket and ratchet. Repeat the procedure on the broiler burner if one exists.

6. Connect the gas line to the stove and tighten the fitting with the adjustable wrench. Turn the gas supply on for the stove and push the appliance into place against the wall.
