JennAir Over-the-Range Microwave E61, E62, E63 Sensor Circuit Codes

On JennAir’s over-the-range microwave page, the three codes E61, E62 and E63 all concern the oven sensor circuit and what it told the control board. E61 says the circuit is open. E62 and E63 both say it is shorted.

Suspects

All three list the same possible problem: the Sensor, the Appliance Control Board, or the associated wiring. Why E62 and E63 both exist for one shorted condition goes unexplained by the page, and so it does here.

Which sensor

JennAir writes only “the Sensor” and “the oven sensor circuit”. It never names a temperature sensor, gas sensor or any other type for these codes, so do not assume one. For codes that name a sensor outright, see the related list.

Owner reset

1. Switch the circuit breaker off for a minute.
2. Switch it on.
3. Monitor the microwave for another minute to see that the code does not display again.
4. Verify the microwave operates.

After that

For E62 or E63 returning, JennAir states that assistance from a qualified technician may be needed. E61’s entry lists only the reset. Finding an open or shorted circuit means testing the sensor, the board and the wiring, which requires opening the microwave, so it is not a job for home.

Answers to two questions

Do E62 and E63 differ?
JennAir words them identically, with the same shorted circuit and the same suspects. What separates them is not stated.

Does E61 rank above E62?
No such comparison appears in the source.

• E21 and E22: open and shorted again, but with the thermal sensor named
• E11 and E12: the gas sensor
