How do I warm up the oven to 200 degree celcius

Hi, it won't cause your oven overheating by hanging loose. I think your thermostat is faulty. I don't suggest opening it to try and repair it yourself. If your tamper with the metal plates inside, your temperature will not be accurate as where you set it for 120 degrees Celcius or 248 fahrenheit it will meybe give you a true temperature of 220 degrees celcius or 428 fahrenheit which would be chaos. Rather rplace the complete thermostat unit.

Hi Nancy,
180 degrees Celcius is about 360 degrees Fahrenheit.

180 degrees c is equal to 350 degrees f (356 to be precise)

If you have the use and care manual, check to see if your unit has the option to change from farenheit to celcius. If so, make sure yours was not accidentally changed to celcius.

Hello, Thank You for using FixYa. I will be helping you today.Your oven ignitor is bad. Replace the ignitor.
Thank You and please rate my answer if it was helpful..

That is actually very hot in fahrenheit, around 482 degrees to be exact. Is that not hot enough?

175 degrees Celsius is equal to 347 degrees on the Fahrenheit scale.

The conversion formula is
Fahrenheit temperature = (9/5 x Celsius temperature)+ 32

Good Luck

if you cant program it for more than the 270 you may have changed it from farienhiet ( bad spelling) to celcius. pushing and holding broil may switch it back.

Many ranges show a beginning temperature that is higher than actual temperature, then the gap closes as it heats up.
Use a accurate oven thermometer to check your temps.
If it is faulty, it will not recalibrate to offset 200 degrees. You will have to replace the ERC.

check for a blown fuse or tripped circuit breaker...It is most likely the fuse..
