Kodonn June 29, 2018 for Model Number Pvm7020skiss After a power outage in my area when power came back on the control panel was “asleep”
1 Answer Hello Kodonn, I'm sorry but we will need to ask you to please post a new question including the verified model number from the units' I.D. tag since the one provided will not come up for us as a valid model number. Thank you for your patience and understanding in this matter. Read More...
Katy Green June 13, 2018 for Model Number JNM 15415 SM5 SS Microwave doesn’t heat every thing else works
1 Answer Katy, if " every thing else works", then the issue is not the fuse. If the fuse were "blown" or a TCO was open, the microwave would be "dead". You'll need to start by checking the door switches and wiring Then the control board for burn marks, crackes and damaged components on the board. Read More...
1 Answer Teresa, It's not likely the fuse. If the fuse "blows" it has to be replaced, before the microwave will operate again. There are several TCO's (thermal cut outs) that react to the temperature in the microwave(hood tco, magnetron tco, cavity tco,etc) When areas of the microwave, or a component overheats, the tco "opens" and turns off. When things "cool down" the tco "closes" and the microwave is operable. Quite often the issue is due to a weak or inoperative cooling fan WB26X10105. Read More...
Lax March 30, 2018 for Model Number Emerson model number MW8119SBM My fuse is blown! I don't know the part number can you tell me what part number should I order?thank you
1 Answer Lax, We do not have any information on Emerson products but could use the fuse WB27X10928. Read More...
1 Answer Ann, The model number you supplied is incorrect or incomplete. But, if you need the 120 VAC / 20 amp, in line fuse for the microwave, the part number would be WB27X10928 / WB27X10388 Fuse. The part is in stock and available at this time. Thanks, Read More...
1 Answer Hello Ed. You will need to remove the outer cover off the microwave to access and replace the fuse WB27X10928 in the unit. Some models the grille and control panel can be removed and they are behind it. You can look there first without uninstalling the microwave. Make sure you have the power disconnected to the unit. Thank you. Read More...
Jane February 23, 2018 for Model Number GE Microwave Model JVM1540DN1WW After a power failure everything in my house worked beautifully including the microwave EXCEPT it does not heat. I am a 70 year old women with respect for electricity, but little funding and the house has a purchase offer on it! I replaced the diode, (reasonable inexpensive and another forum suggested it) but it did not help. In the case of a power failure/surge, what is the first line of resistance? Logic should be a fuse. I have not found where answers clarify a microwaves line of defense/failure. I would think a the unit should be programmed with something to stop major damage if it gets too much power? What do you think it most likely is? The thought of trashing and replacing the entire working unit (less heat) disturbs me if a minor repair is possible. The cost of a repair persons labor and trip charge (very rural location) seem to not be cost effective unless I can do it myself. Most of the items (sans the high dangerous capacity to store power after unplugging) appear to be rather straight forward with access being reasonable. I have a voltage meter but unfortunately do not know how to set the switches on it correctly for this testing. Should I give up,and just use a small table top one for cooking and just use the fans and light for my range cooking with this beautiful looking appliance?
1 Answer Jane, With the unit coming on but not heating and the diode being good, this would likely be an issue with one of the thermal cutoffs that are on the unit, a door switch or a magnetron that is bad. If you know someone who knows how to use a meter I would recommend testing these parts. Read More...
Joan November 20, 2017 for Model Number JVM1540SM5SS The turntable and the heat are not working. Everything else, clock, vent, lights, etc. are working. I checked the main circuit breaker and no change in function.
1 Answer Joan, You will want to check the door switches as it sounds as though one of them may have failed. Normally for this type of issue it is the primary switch which would be the top one. Read More...
Helen October 25, 2017 for Model Number JVM1870sf001 GE Profile Microwave purchased and installed on 4/8/2004. Everything works as usual EXCEPT there is NO HEAT. Profile Model today is the same price -- $599.00 or so.... Other models/manufacturers sell over the range models in the $200 to $275 range. Questions: Is it worth the effort to try and repair....and if so...where to start? Thank you.
1 Answer Hello Helen. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron. Read More...
1 Answer Hello Francisco. You will need to locate the noise filter board WB27X10519 in the unit. Remove the outer cover to see it. The fuse is on the board. Thanks. Read More...
