Amana arg7800ww oven will not come up to temperature.

Hi,

please check that the oven isn't leaking heat into another area. Or maybe your settings need some calibration or the temperature sensor for the oven is off by 60 degrees. If this is the case, changing the temperature setting to 410 should bring the internal temperature to 350 degrees. Please try this.

Thank you.

replace the oven temp sensor, it looks like a metal rod sticking out from the inside back wall inside the oven. part here....

either its the oven sensor rod located at the top of the ovens cavity,or your bake element could be getting a hot spot which is when it gets a discolored spot in the element and can no longer pass sufficient current to heat the oven past 250 degrees

Hi,

If your electric oven is taking too long to heat or just not heating up right, then check out this tip that will give more detail about your problem.

Hi, F2 error code on the Amana Oven means "Oven too hot" You have to replace Oven temperature sensor to fix it.
F3 error code means "Open or shorted oven temperature sensor". Yo also have to replace Oven temperature sensor to fix it.

Summarily, both code has to do with the temperature sensor which you need to replace...

It could be either . The sensor can be checked with a good meter room temp should be around 1200ohms and change with added temp.

Hello there:
Whenever you get the dreaded f-3 code this is the code that tells you that the temperature sensor is going bad or already has gone bad and needs to be replaced immediatly. It should look something like this and cost about 50 dollars

The top element should come on when Broiler is selected. If both ovens have a broiler mode, then look for something failed in the circuit for the broiler heating elements (it's unlikely both broiler elements would fail together.). If there is only 1 oven with a broiler, look for a failed broiler element.

The broiler element on the top of the oven comes on during the preheat cycle to speed things up and then only the lower element keeps the temperature steady. One of those elements is bad, probably the broiler. Try using the broiler and see if it works. If not, you need to disconnect the elements from the oven and check them with an ohm meter. If gthe elements check out ok, then it must be the temperature sensor/thermostat.

The broiler won't turn off even when you press the "Off/cancel" button? It sounds like the broiler control relay is stuck shut. The F3 code means the oven temperature sensor has failed, this probably happened because the oven got too hot when the broiler was stuck on. There is fail-safe thermal fuse that will blow if the oven gets too hot, so the oven won't melt down but you should leave the unit off so you don't blow the fuse.

To fix the relay, you will have to replace the oven control module. I think this is about $200 and not too hard to replace if you are somewhat handy. The temperature sensor is also serviceable, you can find parts at Appliance Parts Pros on the web. Hopefully you haven't thrown the range out yet, let me know if you need further assistance.
