Checking Oven Sensor

The oven sensor is normally located in the oven cavity towards the top. To test in for faults disconnect the power to the oven then remove the sensor. You will need an ohm meter to test the sensor, most oven sensors should read about 1100Ω at room temperature 60 – 80 °F (15 -27 °C), if the sensor reading is ‘open’ or extremely high this means the sensor is faulty and needs replacing, if on the other hand the reading is extremely low then the sensor has shorted (check for wires touching each other) and will need replacing as well.
Return to top

Checking Fuses

Fuses are extremely easy to fix/replace but can be indicative of a larger problem, fuses are designed to ‘blow’ to protect circuitry from surges in power etc, so if a fuse keeps blowing (doing it’s job) the problem is probably not the fuse but something else, so get the appliance checked out. To replace the fuse

  1. Disconnect power
  2. Gain access to the back of the ERC (most fuses are located here)
  3. Remove the suspect fuse
  4. With an Ohmmeter test the fuse for continuity, if it fails the fuse is faulty and needs replacing.

The F1 Error

On a number of ranges this can mean a number of things, the most common being a failed ERC(EOC, Clock assembly)or a faulty touchpad. Firstly if you are using a recent Maytag range it may pay to test the oven sensor as described above as this may cause an F1 error if faulty (may apply to some other ranges as well) this is not a common cause but is worth discounting. To check the ERC and touchpad

  1. Disconnect the power
  2. Gain access to the back of the ERC
  3. Disconnect the ribbon cable that connects the ERC to the touchpad
  4. Check nothing will short when power is reconnected
  5. reconnect the power and switch on
  6. Watch for F1 and listen for the beep
  7. If you get the F1 and the beep this means the fault is with the ERC and it will need replacing
  8. If after 30 mins you do not see the F1 error and hear the beep, replace the touchpad
