How to remove the oven light switch, door latch assembly, and hi-temp cutout on a Thermador CM302US oven

Posted by Samurai Appliance Repair Man, in Oven-Range-Stove Repair 06 September 2011 · 1,564 views

Master Reg illumines us:

from page 35 of the C302 service manual


Turn off the electrical power circuit to the oven at the main junction box before servicing this unit.

When you work on the oven, be careful when handling the sheet metal parts.
There are sharp edges present and you can cut yourself if you are not careful.

Refer to Figure 19 on the next page for the following steps.
1. Turn off the electrical power to the oven.
2. Open the oven door for the component you wish to remove.
3. To remove the upper air vent grille, remove the four bottom screws and the two front oven door latch screws.
4. To remove the lower air vent grille, remove the two front oven door latch screws, (see Figure 18),
then pull the posts on the ends of the air vent grille out of the catches in the chassis.
5. To remove the oven light switch, disconnect the wires from the terminals, press in on the locking arms,
and push the switch out of the vent (see inset 1).

6. To remove the oven door latch assembly (see inset 2):
a- Use a 1/4" ratchet and a 1/4" thin-wall socket and remove the two front hexhead screws from the latch bracket.
b- Pull the latch assembly to the right so that the flange on the left side clears the bracket,
and then pull it forward as far as the wires will allow.
c- Remove the wires from the switch connectors and the motor wires from the main harness.
d- To replace a door lock or door unlock switch on the latch assembly,
remove the two screws from the switch body, and remove the switch.


How to test the touchpanel keyswitch contacts in a Maytag MDB dishwasher

Posted by Samurai Appliance Repair Man, in Dishwasher Repair 04 September 2011 · 1,352 views

Master Reg lays out the drill:

Checking keyswitch contacts:

Unplug dishwasher or disconnect power.
Remove connector P1 from the control board.
Using the table below,
measure the resistance across the switch when the key is pressed.
NOTE: The meter must be connected with the proper polarity.
This test will not work on models with a “touch sensor” type user interface.
The resistance reading should go from infinity (open circuit) with the key open
down to a readable Ω level with the key pressed.
The level may be different depending on your meter, since there is a diode in the circuit.
If available, you could use the “Diode Test” function of a digital meter,
which will give a voltage to turn on the diode in the circuit.
➔If any switches fail this test, replace the console panel/keypad assembly.
➔If all switches test OK, replace the machine control board.

Check your notification settings for your watched forums and topics

Posted by Samurai Appliance Repair Man, in Forum Tips 02 September 2011 · 815 views

I upgraded the forum software to the latest version. Went pretty smoothly and we're sporting a clean new look with lots of cool new features. But, as always, there's bound to be a glitch or two. One in particular that's come to my attention is the notification settings for your watched forums and topics.

I noticed I wasn't getting notifications of replies to topic that I had posted in. I also wasn't getting notifications for new posts in forums I'm watching. Have had others message me about this, too. Turns out this is a "known" issue with the upgrade; known to developers but not to me!

But no biggie-- the fix is easy: just check/reset your notification settings in your control panel.

Watch my short screencast that shows you how to do this ==> http://screencast.com/t/v2oCSzRdY

How to disassemble the door on a Frigidaire range oven to clean the glass

Posted by Samurai Appliance Repair Man, in Oven-Range-Stove Repair 28 August 2011 · 3,609 views

The job is done and my wife is very happy.

For those of you out there who are like me and new to self appliance repair I wanted to post a few of my own details in case someone else stumbles across this post with a similar issue.

  • As Kurtiusinterupptus explained above, there are two tabs at the hinges that pull down toward the door and then lay flat to allow the door to be removed. Once these are down you close the door, it will not close all the way, so do not try to force it.. There will be a 8" or so gap like you may leave open if you are cooling the stove off. Once you meet this point simply lift straight up and out and it should come free. The door is not too heavy, but be prepared to take the weight.
  • For this model there are screws on the inside panel (facing up or topside if you laid it down with the handle facing the floor) and on the bottom edge that need to be removed.
    • There are six screws on the inside panel (3 per side), but only the ones that need to be removed are at the top (opposite the handle).
      • I took out all six, but found out the bottom four simply hold in the hinge assembly, so I put them back in.
    • When you remove the two screws that are through the handle, remember that this will release the handle from the door. If this is the only thing you have propping up the door (mine was laying flat, handle down, on a towel) the door will drop the two inches or so to the floor. No harm done for me, but I wished I had thought of it before.
    • The handle screws are held in place between the door panels by a metal bushing type thing (it certainly has a proper name that I do not know). They just sort of fell out on me, and I had no idea what they were, which was a little distressing at first as I was trying to make careful note so I could put it back together. I figured out what they were and really appreciated them when I put things back together as they made getting the screws though the outside panel a breeze at the were held firmly in place.
    • There are 4 screws on the bottom edge that all need to come out.
  • The inside panel will lift right out at this point and can be set aside. The inside glass is held in place by screws so there was no risk of it falling out.
    • I cleaned the glass lightly with windex, then water.
  • The glass for the outside panel just sorta sits there, so don't go picking up the door or it can fall out.
    • I cleaned this lightly as well with windex and water and just left it in place the whole time.
  • For reassembly, I set the handle screws through the inside panel and though the locking bushings I described above and they stood up nicely. Dropping the panel into place and getting the screws through to the other side of the outside panel was a breeze. Once it was through, I stood the door up and held the two panels in place with my hands.
    • There is a little bit of finagling that you have to do to keep pressure on the panels while getting the handle in place and screwed down. I wish I had had help for this step, but it's possible on your own.
      • It was during this step that I noticed there was a bunch of gunk built up on the outside panel under where the handles go. I never saw it before as I left the door face down the whole time. I cleaned it in place while holding the door, but in retrospect, I would have taken the outside glass out while the door was disassembled, turned it over and cleaned it.
    • The bottom 4 screws will zip right in.
  • Putting the door back on is just the reverse of the removal step above.
Thanks to Kurtiusinterupptus and Kdog for responding to my post.

I hope my additional ramblings above are of use to someone.
