THERMOSTAT

Hi James, Thank you for your question. The part should be Closed and when this part trips once the inside of the cavity overheats and exceeds the recommended temperature, then it is Open. We hope this helps. Thank you and have a great day!

Hello Peter, Thanks for your question. You may wish to test the door switch and thermostats for continuity with a multi-meter and replace them if they do not show continuity. If all of those parts are intact, consider replacing the control board. I hope this helps.

Hello Angel, Thank you for your inquiry. I would check the fan motor and the door switches. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!

Hello Ronald, Thanks for your question. This can arise due to the thermostat, door switches, or the control board itself. Unfortunately, only a licensed technician should test these parts due to the electrical charges that the microwave can have even with the unit unplugged. I hope this helps.

Hi Steve, Thank you for your question. There are some parts that you will need to check to see which one is causing the issue. You will need to check the line fuse, the halogen lamp, the terminal micro switch, the monitor switch, the thermostat and the diode cable. I hope this helps. Thank you and have a great day!

Hi Steve, Thank you for the question. I suggest testing the door switches with a multimeter to check the continuity to determine of one of them are defective. Hope this helps!

Hello Eric, thank you for your question. I would recommend checking the fuse to see if its blown again. If it is, I would recommend testing the thermostat along with the fuse. If the fuse is not blown, the turntable motor might have failed. It would also be worthwhile to check the door switches as well. If the switches, fuse, and thermostat are replaced and the unit is not functioning the issue could be the electronic control board itself. I hope this helps!

Hello Carlos, thank you for contacting us. Part number PS1481237 will trip if the microwave gets too hot. To avoid unnecessary overheating please make sure there is adequate ventilation for your microwave oven by leaving at least 10cm of space behind and on the sides of the oven and at least 20cm of space on top. Where you have already tested the thermostat, we would recommend testing the door switches. You can test your door switches with a multimeter. First, unplug your microwave. Some door switches have only two metal prongs extending from the body, while others have three. Those with three terminals will have a common (COM) terminal, a normally closed (N.C.) terminal, and a normally open (N.O.) terminal. Those switches with only two terminals will have either a common terminal and a normally open terminal, or a common terminal and a normally closed terminal. We are providing directions for testing a door switch with three terminals. If you are dealing with a door switch that has only two terminals, ignore the part of this test that does not apply to you. Using caution, remove all wiring harness leads from the switch's terminals. Use your ohmmeter to test your switch for continuity. Begin by setting your ohmmeter to measure resistance at a scale of Rx1. If you are using an analog meter, touch the metal tips of the test leads together and zero your ohmmeter by adjusting the thumbwheel in the front of the meter until the needle reads '0' on the scale. Touch one meter lead to the COM terminal and the other lead to the N.O. terminal. Do not push in on the actuator. Your meter should give a reading of infinity, meaning the circuit is open, and there is no continuity. Without moving the meter's leads, press down on the actuator until you hear a 'click'. With the 'click' of the actuator, the meter should produce a resistance reading of zero ohms. This means the circuit is closed and continuity is present. (Switches with only two terminals do not 'click' when actuated) Keep the meter lead that is touching the COM terminal in place but move the other meter lead from the N.O. terminal to the N.C. terminal. You should receive a reading of infinity when you push in on the switch's actuator. When the actuator is released, you should receive a resistance reading of zero ohms. Now, set your ohmmeter to its highest resistance scale and touch one meter lead to the N.O. terminal and the other meter lead to the N.C. terminal. The resistance reading between these two leads should be infinite. Finally, take a resistance reading from both the N.C. terminal and the N.O. terminal to any metal mounting hardware that is a part of the switch assembly. You should receive a normal reading of infinity. Any readings that differ from the ones presented here are indicative of a defective door switch that will need to be replaced. Primary Door Interlock Switch part number PS237015 and Monitor Switch part number PS237409. We hope this helps. If you need help placing an order, our customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

Hello Ronald, thank you for reaching out. We suggest that you check the fuse, door switches, thermostat, and display control board, for any damage and replace the defective component to resolve the problem in your microwave. Please reach out to customer service if you need help placing an order, anyone will be happy to assist you. We hope that helps.

Hi Daniel, thank you for the question. Based on the description that you have provided, we would recommend checking the power control board, part number PS1018328, to fix the issue. It manages the power to various microwave functions such as heating, lighting and turntable operation. We hope this solves your problem!
