    Default HGS3052UC/01 Bosch Gas Oven Temp Off 50 to 75 Degrees

    Model Number: HGS3052UC/01
    Brand: Bosch
    Age: 6-10 years

    Bosch gas oven model HGS3052UC/01 runs 50 to 75 degrees below setpoint. I need some help on diagnosing the problem. Is there a calibration to adjust or ohm readings to check on the sensor? Any help is appreciated.

    Hi,

    Most sensors today are 1000-1100 ohms at room temp ( 70F ).

    Bosch doesn't say theirs is any different.

    Hi Jeff,

    I did not find any info on Bosch sensor readings, so, thanks for the info, I will check the sensor. Looks like the sensor may be connected to the board where the digital read out is, is that right?

    Thanks,
    Mike

    Should be yes. Sensor changes resistance to tell the control what is happening.

    Hi Jeff,

    I checked the resistance of the sensor and it reads 1.068K Ohms at 71 Degrees, looks like the sensor is ok. What is my next step?

    Thanks,
    Mike

    If the sensor is good, that leaves the controlling device(s) as the trouble makers.
    Relay board would not be my prime suspect. The clock/control would be the prime suspect.
