If you are required to fit a new temperature sensor to a Mealstream 501 oven on a service call,
you need to follow the procedure below to verify that the sensor is holding firm in the pocket.
The diagram below shows the area of the thermistor causing the problem. This problem has been
eliminated by increasing the hole depth in the temperature sensor pocket thus allowing the
thermistor to goes further into the pocket and lock into position.
The temperature

been modified to
accommodate the

sensor.
