Question about Kitchen Ranges
The oven temperature indicator light does not turn off when the oven has reached the desired temperature.
The oven works fine and by using a thermostat I can validate that when the desired temperature is reached the elements turn off.
Moffat stove model MRMF3150VM-2
I had what seems to be a similar problem with my range, which is a KitchenAid KGRT607HGL6. I'd turn it on, and sometimes it would light, sometimes not. If it didn't light, I'd start smelling gas and I'd have to ventilate the kitchen. If it did light, it took forever to heat up.
That said, I have just finished doing the things I'll describe below, and the oven appears to be operating correctly now. I'm not going to go as far as to say this will work for you, and I'm not even sure which step was the key (maybe it was a combination of everything), but I'll tell you what I did.
PLEASE be careful. Gas isn't something to be messed with. If you have any doubt, you're far better off calling a repairman than blowing the side of your house off, or worse, hurting yourself.
It might help to download this parts list, and refer to page 9, so you know which parts I'm talking about:
Here's what I did:
1. Removed the racks from the oven.
2. Removed the pan from the bottom of the oven (it just lifts out).
3. Removed the flame shield by taking out the 4 screws holding it down.
4. Turned on the oven, and saw that the element glowed, but that the gas took forever to ignite. When it did, the flames were weak, shooting out perhaps 1cm from the burner. NOTE: For whatever reason, if I opened and closed the oven door every 30 seconds or so, the oven would start. If I just left the door closed, no such luck. ANOTHER NOTE: If I started to smell gas while I was standing by the oven, I shut off the oven, opened some windows and tried again later. I'm not a fan of emergency rooms.
5. Shut the power off to the oven.
6. Unscrewed the ignitor from the bracket that holds it in place inside the oven at the back.
7. Wiped off the burner element (there was a little buildup, sort of like gray dust).
8. Unscrewed the bracket holding the burner to the oven, allowing the burner to be moved around (can't be entirely removed, just wiggled).
9. Removed the storage drawer from under the oven.
10. Using a hose attachment, vacuumed all around the area where the valve and regulator send gas up into the burner (about center, back under the oven). Look for a brass nut sticking up into the end of the burner tube. With the burner unscrewed from its bracket, you'll be able to lift the burner up a bit and vacuum around it a little better.
11. Reattached the burner and ignitor to the bracket inside the oven.
12. Turned the power back on to the oven.
Then I turned the oven back on, and the ignitor glowed for 30-60 seconds and then the gas kicked on with much more flow than before, (core flame cones about 1.5 cm long with more even flame out beyond the cores) and the oven heated up immediately. I'll replace the flame shield, oven pan and racks when it cools back down.
My guess is that there was something (lint, cobweb, dust bunny, who knows) partially blocking the gas flow into the burner tube.
One other thing I did after the oven seemed to be working was to adjust the air shutter at the base of the burner tube, right where it meets that brass nut under the oven. I got that from Installation Step number 28 (page 6) on the following PDF:
Like I said, I don't know if my solution will work for you. Try it at your own risk, and DON'T DO ANYTHING BUT SHUT OFF THE OVEN IF YOU SMELL GAS. :)
