This Maytag range model MGR5755QDB
was off by 75-120 Deg. F.
I check the oven temperature sensor and it had proper resistance (1050 to 1100 ohms at room temp.)
To repair this range I replaced the oven control board, part # 74009217
I hope you find this information helpful.
This is the Oven Temperature Sensor if you need to order one, part # 12001655
