Video caed G4MX440 model 8866 There is a jumper JP 5oo on top side of boaed what is it for


Searching various forum threads still availble for this 10 year old card finds that this is a backup/flash ROM of some sort. It seems like each position is a video BIOS version for the card, potentially allowing you to flash a different BIOS to the board. If your board appears dead, you move the jumper into the 2nd position, power up the PC, and move the jumper back to the first position while the PC is still running and then flash the BIOS with Nvidia's NVFlash utility.
Search Google for "MX440 8866 jumper" and the first thread seems very relavent.

WHY DOES MY BOILER PUMP CONSTANTLY RUN


Hello anon, this sounds like there is a problem on the electric side of your boiler. Depending on the boiler if its a combi type it is one of the pcb's calling for the pump to run. If at all possible call a specialist who deals with Central Heating and dont try and fix it yourself.

Need to find a link to the owner's manual/ repair manual for the Grundfos up10-16 b5/atlc......


Following link shows links to grundfos and grundfos manuals.
http://waterheatertimer.org/Water-heater-recirculation-system.html#Grundfos

1) My grundfos stopped working because sediment clogged the pump, and the motor slowed.
When motors slow, they get hot and burn up.
I ask my friend who rewinds motors how to fix it, he said in the old days, they rewound every motor, but today they throw valuable scrap into landfill, and then buy new motors from China.
I told him not to retire, but go to school and teach kids how to rewind motors, and then took apart the grundfos line and cleaned it out with CLR, but it never worked again.

2) If timer stops working, but pump still works, you can buy cheap plug-in timer and connect grundfos to the cheap timer

Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

Everything works except for ther forward and backward rotation mechanism. When these buttons are pressed there is a buzzing sound perhap indication a motor problem?


This is a very common problem with these old Kodak projectors and is caused by a small part called the solenoid link that can be purchased separately or as part of this kit: https://www.micro-tools.com/store/item_detail.aspx?ItemCode=KODAK-KIT

There is also a guy on eBay, "atomk", who sells kits with very clear instructions on how to repair this problem yourself. Search for "Kodak Carousel Projector ADVANCE Repair Kit".

Good luck!

Need replacement microwave to fit existing trim kit


Finally built up the courage to call GE Appliance number and weave my way through the phone menu system. Pressed the right menu option (sales) to speak to someone about trim kits. Found out that the trim kit model number is JX1527MWW. Then called back to select a different menu option (other) and learned from someone else that since the trim kit model is more than 1-2 years old, there's a slim-to-none chance any new microwave models will work with it, and even if there was they couldn't easily cross-reference against a model that old to tell me which one (or something to that effect). So I hit a dead end. Only option for me at this point is to buy a new microwave with new trim kit.

(Personal note: I think the trim kit business is a racket, in bed with the microwave manufacturers. Why else would there be no standard dimensions for microwaves by now--like refrigerators have--and why is it a few pieces of sheet metal cost over $150? Pretty convenient that every microwave model needs its own trim kit model!)
