Question and Answers


GR475LXMS-0 Alarm code E4 F3, replaced lower temp sensor. Still having same alarm?


I posted the error codes that are listed for that model of range in the second image below. The first image shows a wiring diagram with the circuit for a lower oven sensor probe traced in wire colors. According to the parts diagram for your range, it appears to only have a single oven and a warming drawer. That E4 F3 code may be indicating that the sensor for the main oven is electrically "open". You can unplug the range and check that main oven sensor for resistance using a volt/ohm meter. Here is a brief video that shows how to test that sensor. That sensor should measure around 1080 ohms at room temperature. If that sensor is bad, then replacing it may fix your problem. The part number for that main oven sensor probe is 8274149. You can order that part from this page: Whirlpool Range GR475LXMS0 Oven Sensor Probe . Be sure that you unplug the range before accessing and replacing internal components.

If that sensor is okay, you can check the resistance through that entire circuit from the clock control board in the console (violet and tan wires). If you detect high resistance through that circuit then I recommend that you check that sensor wire harness. The disconnect plug at the sensor itself is the most common area of failure in that harness.

If that main oven sensor circuit is okay, then you probably have a bad clock control board in the range. Replacing that component should fix your problem in that situation.

I hope that this information helps. If you need more assistance, reply with additional details.
