Noise in upper right (roof) of Frige

The Maytag has started making a fairly loud gear-grinding, rattely, clock-mechanism sounding noise coming from the top of the frige side, behind a panel on the roof of the interior above the lights. It runs quite a while then goes silent. I don't yet see any indication of operation problems. What's up?

    I can't find such a part or number in the diagrams for my unit (on partselect.com). The wiring diagram doesn't describe such a device either. I'm wondering if what I'm hearing could be electrical arcing noises... though it sounds mechanical and goes on for several minutes. It comes from where the adaptive defrost item mounts... clearly that area. Any other ideas?

  • John Nagy Mar 15, 2007

    That's the right number. And I'm looking at the diagrams athttp://www.partselect.com/ModelFrames.as...
    Please advise... the noise comes from the area where item 12 and 13 appear to be, inside the covered area on the roof of the frige side, right rear.

    I'm waiting to catch it making the noise again... thanks until then...

  • John Nagy Mar 20, 2007

    Well, I have not heard the noise again, but the frige is not really very cold, while there is no frost accumulation in the freezer (which is plenty cold). I'm very handy with self repairs, but this is so ambiguous... Should I give up and call service? Or are they likely to charge a lot and shotgun it due to the lack of clear indicators?

  • John Nagy Mar 20, 2007

    Let me be more clear; the frige side is turned up to coldest setting, and is maybe 40 degrees. There is a slight detectable cold air stream from the vent under the left light, so it's not altogether blocked.

  • John Nagy Mar 22, 2007

    ...and now the frige is getting warmer...

  • John Nagy Mar 22, 2007

    ...and now the frige is getting warmer... arg!

  • John Nagy Mar 22, 2007

    Frige is up to 52 degrees. No sign of visable frost in frezer which remains cold. Heard the noise again, it is CLEARLY now an arcing sound, loud, even capable of being FELT through the plastic on the top of the frige above the light, exactly where the defroster control unit sits. Should I bail and call service or attempt it myself?

  • John Nagy Mar 23, 2007

    Well, I called for service, they took one look (and it was making the noise at the time!) and said 'Yep a common problem, need a new defrost heater sensor disc and a new defrost board.' Took about 45 minutes and totalled $300 with labor. Now we'll see if it works. There was enough frost inside the coils to prevent air distribution to the frige side. The noise was arcing/bouncing points in the relay on the defrost board. Apparently.

  • John Nagy Apr 13, 2007

    Don't replace the assembly without replacing the sensor disc, which according to the repairman for mine is the CAUSE of the failure of the board. The noise is the relay chattering because of the damage... and a new board will fail if the sensor (small disc, 2 wires, clips onto coils inside freezer) isn't replaced... This took the very experienced repairman near an hour, working fast and efficinetly. Lots of panels came out. I'm not sure you want to do it yourself...

    this is the EXACT problem I'm having with my Maytag side by side.

    The noise described from the upper right hand corner if the fridge.

    Diagram doesn't show any motor. It made a noise like that back in March and a week later, the freezer coils were frozen up and fridge side wasn't cold. Defrosted the whole thing, and it worked for months...although the fridge hovered at just 40 degrees.Then Last weekend the same noise. this weekend, same problem.

    We also had a power outage for about two hours this week, so I don't know if that had something to do with coils freezing up...

John, since you have an adaptive defrost board and not a mechanical timer you can rule that out. It's more than likely your auto-damper motor and gear making the noise. As long as you are cooling ok, it's still opening and closing. Down the road it could fail in the open or closed position, giving you freezing conditions in the refer or no cool in the refer. It's not a bad job to replace, just a pain to get at it. part number for the damper 61005044. Catriver..post back

    John, Im going by the model mzd2766GES which was posted with your question. Is that the right model? Catriver..post back

  • Anonymous Mar 15, 2007

    Number 13 is your adaptive defrost board. Usually they don't make any noise but there is always a first. Number 8 is the automatic damper assy. that I thought might be your problem. This will make some noise if failing. Number 7 is the control slide assy.gear. The part number I have for the auto damper motor is 61005044, the adaptive defrost board is 12002104. Are you have a defrost problem? Heavy build up of ice on the back panel of freezer. I know they had a service bullitin out on the auto damper not working correctly. They issued a new kit. Part number 12001905 (kit). Catriver..post back

John or anyone, can you please show me where to find the Defrost Heater Sensor Disc and provide a part number? My Maytag SidebySide is was making the noise for a month and now the fridge side is no longer cold (58°F). Also, I am going to replace the Adaptive Defrost Board as this is ultimately what failed due to the faulty Sensor Disc.

1998 Ford Windstar. Loud grind sound when started it.

Question edited for clarity and fix funky punctuation and lack of spaces.
Question moved to model category.

My first thought was that the timing belt had snapped, but you have a timing chain and it says this

Does a Ford Windstar have a timing belt or chain?
Best Answer. Your Ford Windstar had two engine options and they both ran a timing chain, not a timing belt. Belts need to be replaced at around 100K miles, but since you have a hardened steel timing chain, you have nothing to worry about. Your chain should last the life of the engine without being serviced.

Has the oil ever been changed. You saying there was a 'pop' concerns me but it may have been a backfire, or unburned fuel popping through the Throttle Body.

And then there is the grinding sound, but that might just be the starter on the flywheel.

The only way to diagnose is to call out a mobile mechanic.

Loud noise

Check for bones/glass/ceramic from chipped plates in the food chopper (for lack of a better term). You'll need to disassemble the entire lower arm unit.

Maytag washer makes loud grinding noise during the spin cycle

if it's making a noise then either your drain pump bearing is going out or your thrust bearing is going out (assuming the noise happens in both spin and wash). Tip the washer backwards so that you can get underneath of it. Take the belt off and spin the pump pulley on the right side. This should spin effortlessly.

The middle pulley is the trustbearing pulley. Spin this--- one direction it should have a little bit of resistance--- the other should have more resistance
