Here are your parts includes a wiring diagram.
Replacement parts for MAYTAG MER5750BAW RANGE- S/C F/S ELE | AppliancePartsPros.com

I could not find a fuse in the unit.

I would start by checking the power.
Try flipping the breaker off/on slowly a couple times.
Sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.

If the above is OK then a wire may have burned off but I cannot say where as the oven and the stove top 240 lines look separate from each other looking at the witring diagram.

You are welcome and I am glad to hear it was a relatively east fix.

And thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.
