I posted this last week and did not get a response.
My range is a Caloric and is propane. Stove top works fine.The oven has been slow in coming on for several years. Recently it got longer and then would not come on at all.
I removed the broiler drawer and tapped on the oven valve with a stick (with the ignitor glowing brightly) and the oven came on and cooked normally. Next time I was unable to get the oven to come on at all. So I assumed that the valve was sticking. I ordered part number AP4102463 I think I should have ordered AP4285640. The only difference appears to be the mounting bracket. Most of the writing on the valve is the same: flat igniter, G-LP and 3.03/3.3 V.A.C. 3.3/3.6 AMP 60 HZ. I installed the valve and the oven burner did not come at all and I waited for al long time. The ignitor was glowing brightly first red then a white/ red. I tapped on the valve and the burner lit near the igniter breifly and went off. At this point gas off and stove unpluged. I measured the resistance of both new and old valve to be 1 ohm, the igniter to be 270 ohms and the control to be 0 ohms. With gas still off I pluged in the range and took voltage readings. Oven control on and incoming was 124VAC, voltage drop across the control was 0, across the valve was 2.25 and across the igniter was a little over 121. Why does the gas valve not open? I have waited for a long time. How long should it take? Is the valve I received bad, is it my igniter bad or am I missing something. Thanks for your help
ANSWER Hello Don. Test for 3.2-3.6 volts AC at the gas safety valve with the igniter turned on. If the voltage is there, you have a bad safety valve. If the voltage is low, you have a weak igniter and the igniter will need to be replaced. If both test good, you have a bad pressure regulator or low gas flow. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
