I have a magic chef range/oven. For the last few months, it has taken longer and longer for the oven to heat up to temp. Now it won't get more than 90 degrees or so. What is the problem??

The temperature sensor in the oven needs to be replaced. Here is the part to order. As far as the top element, lift the top up and look for lose or broken wires on the element. Keep me posted.

Hello & Welcome to FixYa
If the pilot is clean and still won't light then the problem is with the safety valve that won't open and so needs replacement. Please get back to me if you have any other questions.

If your oven is gas, like it says up top, then your ignitor is bad...

this could be a an open probe or shorted probe connection.you need to check your temp probe harness to your main board.
there is a chance that you need to replace your temp probe.
last thing would be to replace the EOC

it is a glow coil , thermocouples are on units with a free standing pilot that you have to light, if you have a range like this you may need a thermocouple if not a free standing pilot you have a electronic gas iginition system that uses a glow coil, you turn on over setting and oven glows orange then iginites if this is what you have you need new glow coil, easy to repalce

OK, you will need to watch the pilot when you turn the temp control. It should get longer and give heat to a coupler that should be attached to your gas valve. If the pilot does not extend when you turn the temp control then the temp control is bad. if it does then your valve is bad.

I hope I got the right kind of machine doing this blind.

you could have a bad ignitor check that it is actually igniting the gas and you can see flame, also check the cavity sensor a probe that sticks into the oven at the top usually on the left top corner but if the bake cycle works with good results them it is ok
check for flame when it starts give it a mibute to ignite, if it does not then you need to replace the broil ignitor.

i have a magic chef gas range. broiler work, burners work, fan works when you turn the oven on, but oven does not get hot. could it be the electronic ignitor or does even have one.

YOU HAVE A BAD ELECTRONIC RANGE CONTROL OR ERC
