We have a Maytag Gas Range, Precision Touch Control 500. The oven quit heating up. When we turn it on by hitting bake and touch the temp up to 400 degrees it always stays at 100 degrees and never heats up. Everything else is working fine, the top burners work fine, the broiler works fine but still the oven does not heat up. Anyone have any suggestions?

If electric turn the oven to bake and look at the bottom element. If if does not turn red hot, it may be defective.
If gas, turn to bake and watch the igniter to see if it get red hot. If not, it may be defective.

Either both bake and broil elements are burnt out (highly unlikely) or your control / clock may be bad. Also check to be sure you have 220v going to unit.

The heating coils in the oven need to be inspected very carefully where they plug in to the oven wall. You will need to remove the back covers and check the insulators and wiring harnesses. Over time the insulation can break down and oxidize the metal connections. You can use a voltmeter or test light to verify that the coils are getting voltage from the thermostat/switch. replacing parts is cheaper than buying new if you can find the parts.

check power/ repalce clock assy

you need to replace the oven ignitor

you can replace touch pad and not very hard to do,you may want to replace control board also.

make sure the wire is connected to the ignition(where it sparks)if it is gently clean the sparking surface with a piece of fine sandpaper.Hope this helps,if it still does'nt work you may need to replace this part but it should'nt be expensive and you can do it yourself(usually one screw) ps sorry for the late reply.

sounds like you have a bad oven ignitor, very common problem with alkl gas ranges, easily repaired by you a few screws and a wire harness part number 12400035

Here are the codes for Maytag Ranges:

MAYTAG
Type "C" and "D" Clocks Range/Stove/Oven Fault Codes Failure
Code Condition Check/Repair F1 Supervisory relay enable shorted (non-cook mode); sounds alarm and inhibits cook mode if alarm fault monitor is always active in non-cook mode, and requires removal of power until serviced. Usually a bad touch pad or clock assembly (also called the ERC). Replace touchpad or ERC F2 Bake/broil/clean temp runaway alarm; sounds alarm and resets control to non-cook mode when bake/broil/clean temp exceeds programmed limits. Usually means a stuck relay. Electric @ 525F (bake), 640F(broil), 900F(clean)

Convection oven and Bake will not heat past 200degrees. Broiler works fine and the range works fine.This is for the Model # MGR5875QDW, Gas Precision Touch Control 800, can you help. Thanks Kasz3
