Hey, I've got a faulty oven here that won't heat up properly. The previous owner suspected a defective heating coil, but they are all functional. I tested it with an oven thermometer: if only bottom heat is on, the thermostat switches correctly and the oven heats up as it should. However, as soon as top heat is (also) on, it only heats up to about 80°C (144°F) below the target temperature.

The sensor is located directly behind the upper coil, so it doesn't seem too far-fetched that it switches sooner in this case, but 80 degrees too early? It has been working for the past 12 years... In YouTube videos, a faulty thermostat seems to cause the stove to heat non-stop.

Any idea on how I can fix this? I don't want to buy a spare part only for the problem to persist in the end.

Edit: This is about an IKEA FRAMTID OV9 featuring an EGO 55.17253.120.

I might have phrased that a little ambiguously. The thermostat does not switch off at 80 degrees, but 80 degrees below target temperature (set 150, reached 70).

The replacement thermostat is 40€, which is more than I usually intend to spend on a repair, so it would be a shame to buy it and find that the fault is still there.

That sounds like a zero drift/calibration error. If its got a computer in it u might be fucked. If u got a physical temperature knob u could always just rotate it on the dial by 80C

That's what I thought too, but when I try it with bottom heat only, it switches just at the right temperature.

If its got a computer in it u might be fucked.

The oven only has a display for the clock and the roasting thermometer, the thermostat is independent (an EGO 55.17253.120).

If u got a physical temperature knob u could always just rotate it on the dial by 80C

I really want to avoid that.

Whether it be electronics, automobiles or medical equipment, the manufacturers should not be able to horde “oem” parts, render your stuff useless if you repair it with aftermarket parts, or hide schematics of their products.
