ZISB420DKB (2016) General Electric Refrigerator - Instructions

Replaced dispenser door flapper by following the do it yourself video in this site. It was really easy. Just be careful when removing the dispenser black bezel. I broke one of the little tabs when taking it off.

Removed face plate, which holds the circuit board. Removed the next section be removing the 4 screws that hold it in place. Then removed the old solenoid, and replaced it with the new one.

Removed escutcheon, removed control panel, remover and replaced flapper, spring and crank. Followed the instruction exactly. Although I hope this fixes the frosting problem, I did not see anything wrong with the parts I removed. I hope this fixes the problem,

Followed the online video. Unplugged refrigerator, removed trim piece, lifted control board cover, removed 4 screws retaining circuit control board and removed the 3 connectors from the control board. Located flapper and removed by using small flat tip to take tension off flapper connectors. Helper held flash light to illuminate flapper connectors. Reversed procedure. New flapper seals well and cured problems. Circuit board was a bit different than one in video, but still had the 3 connectors. Marked each connector with grease pencil at top edge to ensure correct reconnection. Should note how wires are threaded around circuit board to ensure they are tucked back in correctly in reassembly. Remove trim piece carefully. I broke 2 of the 8 plastic pins that hold trim on. May be due to age of unit as they were brittle. 6 pins still hold trim piece flush.

First tried just replacing flap/spring and mounting. Still did not work so then order a new solenoid with piston that attaches to mounting. That solved problem completely. Corrosion around piston prevented fluid movement of flap. Easy fix after watching video. Saved a bundle I'm sure. Thanks !!!

Researched on internet/you tube; ordered part, and did the repair. Easy to do and saved the cost of a service call.

Pop off the control board for the ice selector/water. Remove power / signal connections. remove four phillips screws, Remove plastic hopper. Pop off Ice door gasket, pop in new one and put back together. If you fridge was sounding like it was speeding up and slowing down, this will correct this problem as well.

I only had to remove the old filter and install the new one - all by hand. I then ran about 1 to 1and1/2 gallons of water through the filter to clear it.
A WORD OF CAUTION - HOLD YOUR GLASS CLOSE TO THE WATER DISPENSER FOR THE INITIAL FILLING - IT WILL SPIT UNTIL THE AIR IS PURGED FROM THE SYSTEM!!!
An extremely easy repair.

I removed the door cover plate and disconnected the circuit board, then four screws. The part was corroded in place. Upon removing three screws and cleaning the surface, the new part was an exact fit, replaced it and everything works like new.

repair was easy, just removed control panel and removed screws from solenoid, switched out with new, was done in minutes

Replaced rusted solenoid.

Popped front button panel off from the bottom using flat head screwdriver; Removed 4 screws holding electronics board and disconnected wires. Unscrewed 3 phillips head screws on old solenoid and replaced with new part. Reconnected wires to board, screwed back in, and pushed panel back into to place.

Thumbs up to PartSelect - fast, straightforward service and fast delivery.

I followed they instructions from the other "do it your selfers" but only replaced the solenoid. This was the cause. Rust was keeping solenoid plunger from moving and this held the flapper door open. Very easy to repair!

Unscrewed old cartridge, ordered new cartridge, installed new cartridge by following very simple instructions. Took only one day for part to arrive from PartSelect although I paid for cheapest shipping, which was "ground." I was amazed!

Took old one out with my fingers. Put new one in with my fingers.

Remove control panel.
Remove four screw in control panel bracket.
Remove to bottom screws at bottom of solinid loose top screw.
Replace all screws.
