    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    I've changed the magnetron & everything is now well. Thanks to all that replied with your comments, you really helped me understand this appliance! I still have a question, how come a magnetron gets to have such a reading, is it for rough handling, pollutants in the atmosphere (salty due to...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    Very good post, debe, thanks! My readings with everything isolated are as follows: Power xFormer's Primary = 0.6 ohms & to gnd ~= infinite; Power xFormer's Secondary 0.2--->0.3 ohms & to gnd ~= infinite; Isolated-electrode from xFormer to Diode resistance to gnd = 115 ohms; Magnetron (electrode...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    Yesterday I put another good switch as a monitor switch & put a little oversize fuse at the magnetron circuit but after ~45 secs it didn't even warmed up the little liquid but it made a train-like noise &, after a little over half a minute it started to give off a burning odor: you know...

    Have successfully tested the 'Broiler' function today with the primary of the power xformer disconnected. It remains to try to find another Monitor switch & adecuate power fuse for the last test as a microwave, per se...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    At a test I've found that one of the swithes goes from off to on twice after the door arm start touching its little protution when I'm closing the door. Think, but not verified yet, tbat this short span of time is not only enough for trying to start the fan but also to cause a serious enough...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    At the fourth chat with Whirlpool services was given an unuseful email for contacting them so receved an appropriate mailer message. Did another test with the unit & found something that caught my attention, the circumstances for the test were as follows: ---> main fuse connected, ---> one...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    The magnetron was not connected to anything except by way of been in contact to the chassis (Grounded). Need help finding the owners manual for this unit, could anyone knows a way of finding it? It might prove useful to know that the unit was probably bought at Walmart in Puerto Rico.

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    Have a specific question in relation to the magnetron of this unit (in the case you can't read it clearly, the magnetron shows Galantz M24FB-610A & under this the following string G0316503 GAL03 GEMCS1, the last digit is a small '1' like a subscript but aligned as a regular digit). As mentioned...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    Thanks to you too, ramussons, for replying! Finally stumbled with the model # (wmg09sae). Other info found is Power = 1350 W, grill power = 1000 W & microwave power output = 900 W. I found a 25 A fuse & used it with the primary of power xformer disconnected and all functions well (the needed...

    Sorry kellys_eye to reply today but we had a blackout yesterday, almost all day. Important points: relevant measurements below... ...0.7 ohms primary of power xformer both, attached & disconnected to control board & magnetron; ...infinity to gnd; ...0.3 ohms at magnetron contacts; ...3.3...

    Have been given a disassembled Whirlpool grill-microwave oven with missing decals & fuses?

    Have tried in 2 days & more than 4 hrs to stumble with that model & even chated with someone at Whirlpool but got out empty hands. This unit was bought about 1 yr ago probably at Walmart. It suddenly stopped working but appeared to be on. The son of the owner openned it & took out "2" fuses out...

    Jumpstarting unit PS1100 may be incapable of charging?

    After disassembling the P/S unit discovered it had a blown out power protection unit inside the transformer (see uploaded photo). The written info on the device is as follows: M-F AUP0 Q4 <PS> E <--- the PS & E go inside the 90° rotated square shown 130°C JET 2A 250V~ This squared...

    Jumpstarting unit PS1100 may be incapable of charging?

    I've disconnected the Power Supply to the unit and measured it and it read almost zero volts but it's suppoesed to give ~15 DC volts. I'm in the process of connecting another suitable source. After finishing with this step I'll post the outcome of it.

    Jumpstarting unit PS1100 may be incapable of charging?

    This unit was given to me many years ago but the battery was dead and I left it untouched a long time. I then needed to charge a car battery but it's not performing the job. I would like to diagnose the unit and repair it if not too costly. The power cable is missing but I connected it to the...

    Help in deciding method for de-modulating? a signal to extract one frequency!

    Maybe, it's not clear enough! For years I've been thinking of designing & build a remote controlled sailing-motorized boat & controller. This means that the boat itself should be made by me as well as the receiver at the boat. I've been thinking of using a recorder (the musical instrument) as...

    Aerial (roof) rotating antenna operation?

    I found a couple of dish-rotators from microwave ovens that work & found that they've pretty good torque for the task. It doesn't need to be directly coupled to the small mast so the strain to the plastic pinnions inside can greatly be reduced. The only inconvenience is they're AC powered (115...
