Message on microwave: F1e4 mw power relay. I believe the circuit board needs to be replaced. W11100598??
For model number KMHC319ESS2
Hi Marilyn,
Thank you for your question. According to the Whirlpool website, the F1 E4 error code is letting you know that the microwave could not carry out the function that you selected and there may be an issue with the electronic control board. You can try and reset the oven by unplugging it for 1 minute. Once you have restored power to the microwave, wait 1 minute to see if the error returns. If it does you will need to replace the electronic control board. The part number listed under your model number for the electronic control board is PS12745386. If you would like to place an order for it, you may order it either online or by calling our customer service line and anyone will be happy to assist you. We hope this helps! If you have any questions, please let us know.

Hi Ron, Thank you for writing. If the appliance is operating normally but without heat, we suggest testing the Diode. NOTE: If you are not comfortable doing this yourself, please get an electrician to do this repair. Before you begin any repair please unplug the appliance from the electrical outlet. Use a Phillips head screw driver to unthread the screws securing the grill. With the screws removed, open the microwave oven door then the slide the grill to the left and lift it up to remove. Next remove the control panel mounting screw then lift the control panel up to detach. Then remove the screw holding the inner access panel and then release the panel from the retaining clips. To avoid injury, you will need to release the potentially dangerous charge from the capacitor by using an insulated pair of needle nose pliers to touch both terminals simultaneously. Be careful not to touch the metal portion of the tool. Now remove the screw holding the diode to the frame. Use pliers to pull the diode free of the capacitor. To test a microwave diode, you can use a multimeter. A non-defective diode will read between 50,000 and 200,000 ohms. We hope this helps, good luck with the repair!
The nightmare was that this microwave is installed under the cabinet....in order to get to the light bulb I had to pull out my stove then squeeze into the space between the stove and counter....my old microwave light bult was much easier to change.....Shame on Whirlpool for making this so difficult.....must be a better way to cover the light bulb so that we do not need a screwdriver to remove the door to get to the light bulb
Unless you have a very comfortable background with electronics and electricity, I don't necessarily recommend taking apart a microwave. If you are very handy and are going to be VERY cautious to follow the rules of discharging caps and testing voltages before moving forward, then go for it. That said, I took the microwave off and apart. Not knowing where to find the parts, I was fortunate that the installer put the instruction book for the microwave inside the front vent slot above the touchpad for reference. it details the location of every part and it tells you very clearly what each part you test should show specific to this microwave on your multimeter. Find this guide online if you don't have it. Turn on the microwave for 20 seconds with a glass of water to make sure it's not heating - that with the noise means it's eeither the magnetron, cap, or diode. Read the notes on this site for all of the basic things to look for with the magnetron, diode, and capacitor. Once comfortable with the guide, locations of those devices, and how to test, then take it down and apart. Unfortunately, I didn't do all those things in that order, and it only wasted a lot of time trying to find the parts. Once I found the parts and put all the screws and covers back for all the areas that didn't need to be accessed for the repair, testing went quickly. The diode was bad. Ordered a new one and had it in 3 days or so. That means your microwave will be apart and sitting somewhere for a little while until you get the part and have time to repair it. Putting the diode back isn't too bad. Reassemble the microwave and put it back up again. If i had to do it again, it would take me 20 to 30 minutes once the microwave was down and on a table. Also, I used some bricks with towels over them or you could use some sawhorses to keep the microwave elevated so you can plug it in and run it after installing the new component. Again, make sure you discharge the cap before touching anything again even if you didn't run it, but just plugged it in.
