    . Sir Mahfoudh . . . . . We can't help you in any way, until you look inside the door and copy down and pass on the Model number of that Whirlpool unit. Other than, it is going to be the part that the internal temperature control knob is pushed onto. "I even brought a specialized...

    Need help with obsolete Motorola components.

    . Sir Rowdy . . . . . I thought that you might have picked up all of your marbles / cow chips and went on home. Did you do any further looking into : But what I was initially marking up, was those resistors solder pads, and the bottom YELLOW circled one seems to be floating, can you...

    Need help repair dead switching power supply

    . . Sir Michael . . . . Sorry for the time lag in response, but seems like that I am now being involved with 6 or 7 other assists. Your dim lamp test is telling us, at the least, that the raw dc power supply is properly charging up those two high capacitance electrolytics and that...

    Look at the very bottom pictorial portion of my supplied information sheet and I have a RED B and D boxed, now, between them , find R39, then go up to 34 and then BAMMMMMM there is R40 within a FINE LINED GREEN box I have designated it with. If those voltages are not up in the 100's of...

    Help please !

    On some mikes there is a floating of the actual internal sensing element in a foam wrap or in olden days, and even worse, rubber and it may have hardened with heat and time and is making vibrations transfer in handling, being much MORE noticeable. 73's de Edd

    Resistor inside a fuse?

    Parrallax + reflections yields a ? 91?? 81??11??10?? value. So just break off the left end cap and take an ohmmic reading, just for satisfying curiosity , as its being a metal film resistor and had only reached approx 160 deg F to trip. ( "spell check" . . . . . it don't knose "ohmmic" . ...

    OK your DC mode is NOW correct and your negative probe to the wire from the speaker that is going to ground is correct. Not sure if you are getting to the right place with the + probe so UNPLUG the EL84 and set aside and then CORRECTLY find its pin 7 and fire up the set and see how high the...

    Resistor inside a fuse?

    Sir Saucey . . . . Not abnormal at all to see that "delicate" type of fuse in some situations, its use of a selected resistor and using woods metal as the "solder"medium and letting resistor heat open it up. This case is using a 12 ohm resistor, and you see the pristine resistor, yet...
