Hi,
I have a Hotpoint gas oven (model RGB745BEA3CT) which I purchased new about 5 1/2 years ago. It seems to work okay at first. It usually reached the desired temperature. and stays there a little while. But then, even though the temperature dial hasn't been changed, my oven thermometer reports the temperature changes. Somtimes it goes up 100 degrees, sometimes it goes down.
I thought that maybe it was the oven temperature sensor, but I replaced that, and I still have the same problem.
Any suggestions? I need to take care of it asap, or my wife will not be too happy.
Thanks

If you have an ohm meter, check the resistance of the bake glow bar, should be between 50-150 ohms, if it's not it needs to be replaced.

Thanks I do have an Ohm Meter. What is the bake glow bar, where is it, and which spot on the Bake Glow Bar should I test. Also, I assume you mean at room temperature. Is that correct?

Yes, room temp is good. The glow bar is attached to the bake burner tube. You can remove the bottom of the oven by removing the 2 screws at the back of the bottom panel. Where you want to check resistance is under the oven, remove the bottom drawer, and you will see the 2 wires from the glowbar (white) going to the gas valve, check resistance and let me know

I will try to check it soon. So, I need to check it from the back of the oven, or from the front (once I remove the drawer). If I do need to replace the Glow Bar, what part # is it? How much is it?

Thanks Again,
I am a little confused. First you said the glow bar, but then for the part, it is the igniter. Is the glow bar and the igniter the same thing?

However, when I use the ones category, it comes to around 240- I tried it a few times, and this difference happens every time ( and yes, I have been switching the adjustment dial for each one to make sure it starts at zero). Does this mean that there is something wrong with my Multimeter?

Does this mean that there is something wrong with my Multimeter? Also, I have one more question. I have had gas for my oven and dryer for a while, but I just switched my heat from oil to gas. The gas company had said that the line was big enough.But, could that be the problem with my oven anyway (since all the gas appliances share the same line into the house).
