Whirlpool Gas Oven slow to heat up

We have a Whirlpool gas oven, model number SF387PEYQ4. This oven is around 15 years old.

Recently we have noticed that the oven is taking longer and longer to heat up. It takes even longer if one or more stove burners is in use. Once it is up to temp, it seems okay.

I am fairly technical, and can use a volt-ohm meter when needed. I have repaired our gas dryer, but have never figured out how the gas oven works. I wouldn't know where to begin, and we have no manuals at all.

Any ideas about where I might start to diagnose the problem?

Thanks!!

Can you check the model #? I couldn't get it to work at Service Matters Online I looked at a service manual for a similar stove and found that only the bake valve comes on during bake. Some ovens use both bake and broil for the warmup.When the oven is on, is the flame the same as before? When you have a top burner and the oven on, is the top burner the same as before? Have you added any gas appliances lately? It sounds like the problem might be the gas regulator on your stove. Also, look on the back of the stove for the tech sheet. Test the oven sensor versus the resistance/temperature chart on the tech sheet. Let us know what you find. Thanks.

Daddyjohn, thanks for the reply. I double-checked the model number - and SF387PEYQ4 is correct. It's located with the serial number. You pull out the drawer below the oven and the numbers are on the right affixed to the appliance. It also has clearances and BTU information, and that it is made for Whirlpool corporation.


In answer to your other questions... First, I'll have to get back to you on the flame... Second, we haven't added any gas appliances in over 8 years.

Next, on the back of the stove is what looks to be wiring diagram. I can't move the stove out enough to see it without climbing up and over and dropping down behind and disconnecting the gas line, so I cannot get a good look at it, until I take that leap. Will take some measurements - when I see a resistance/temp chart. Hard to tell upside down, or with a mirror if that information is there at all.

Thanks for your help!

hi deb if you go to www.aervicematters.com and search thru technical reference, you'll come to some service manuals under job aids. Try looking thru them to see if can find your stove. The sensors are pretty much all the same, so if you don't get an exact model # but one that is close to yours, using the chart should be ok. What about the top burner flame when you have the oven and a top burner on? Same as before? Also, most electronic oven controls have a recalibration procedure where you can adjust for a temperature drift. There should be a tech sheet on the back of the stove, it will have the recalibration procedure. Let us know about the flame sizes. Thanks.
