To be absolutely confident that there's no trouble with the replacement (or that the problem isn’t with your heating element or another part of your oven) it's worth contacting a professional. But do be 100% sure that you've chosen the correct one for your make and model of appliance. You can get replacement thermostats from many places. Step 4 - (Most likely) Talk to the professionals If you're getting a reading much higher or lower than that, you've got a problem. If it's as close to zero as possible without actually being zero, it’s fine. Is it reading zero? If so, your thermostat is broken. Touch one multimeter probe to each of your device's terminals. Or, if your device is an older one which doesn’t have one of those, to the 2k or 4k setting. You'll need to set your multimeter to the lowest ohm rating. You can then unscrew the two screws on the back of the thermostat sensor and carefully extract it. Or if you have plastic plugs on your 'stat, you might just be able to pull them free. You'll probably need some needle nose pliers to pull the wire leads from the terminals connecting it to the metal plate. Follow the wires which lead from that metal plate to a plastic plug. It's probably edging towards the bottom right of your oven's back. With the back panel off, look for a rectangular metal plate with two screws in it. Its location will depend on what type of oven you have. But if not, check under the exhaust hood, below the control panel or beneath the backsplash. It's most likely to be behind the back panel, which you'll need a screwdriver (Phillips head) to remove. To the uninitiated, this is probably the most difficult part. Once your oven is unplugged, open the door and take out all the racks and trays. You really do not want it to be powered while you're playing around with it. Or that it is disconnected at the circuit breaker or fuse panel. Important safety notice: always make sure that your oven is unplugged before you start. If you're not comfortable doing that, call in a professional. It's worth noting at this point that the following test will require you to dismantle parts of your oven. Part 3.2 - Testing your thermostat (more advanced version) Or to proceed to a more advanced version of the test… Temperature is off by more than a few degrees: it's time to call for oven repair in London, or wherever else you happen to be based.(If you had to open the door to measure it, it can be as much as five degrees off and still be fine.) Temperature is off by a couple of degrees: your thermostat is in good shape.
