Maytag PBF 2255 HEW refrigerator JAZZ board replacement issue
Jazz board was replaced with new OEM part (unit would not defrost, evaporator coil got iced up, internal recirc fan and defrost heater are both good).
Now green LED displays flash double zero's (0 0). Is the new jazz board the wrong one? Old part had sticker on chip inside that reads "JAZZ 09". New board has chip inside with sticker that reads "JAZZ 14".

I just asked the service dept, "Are you programming the Jazz bd or the controller?: I had my Jazz bd replaced, worked less than a month. had tech come back out and reprogram, worked less than a week So I put old Jazz bd back in and reprogrammed it. So then I put new Jazz bd in and it came up as though it had been programmed meaning that the controller bd was programmed.

If the evaporator is just freezing up around the area where the refrigerant first enters unit, then it may be low freon. When the defrost element is fubar the entire evaporator is covered with ice not just a segment of it.
If your air damper door is constantly getting ice forming on it there is a reson for this. This is most oftern caused by an improperly sealed fresh food compartment door gasket, a warped door or improperly adjusted door hinges. Having said that... there can be other causes such as a clogged compartment drain in eaither compartment that forces air to rapidy transfer from one compartment to the other side when one of the doors is opened and the rapid temperature change initiates the rapid air flow and eventual condensation / freezing.
Make sure your compartment drains are clear and the end of the drain tube that terminates in the catch basin under the unit is free of obstructions. (rear fiberboard compressor cover removal required) To cause the rapid air transfer I spoke of above this tube has to be blocked.
If you discover that the compartment drain is clogged with ice.... the only fix / remedy is to perform a manual defrost by unplugging the unit, removing the freezer contents and directing an exteranl fan into the freezer compartment for just over 2 hours. The reason for the 2 hours is that should there be ice in the drain funnel the water in the top of the funnel accumulates on top of the ice and insualtes the ice in the funnel from melting so you just have to wait until it warms up over time.
After perforning this manual defrost... use a vacuum to first attemot to remove any debris from the drain tube end and then put the hose on exhaust and direct air into the end of the compartment drain tube to float out any debris from the compartment drain funnel.
One question I have is why are you changing Jazz boards? Do you suspect you have an Automatic defrosting problem?
you have a problem here
you need to get the secondary defrost kit installed
it is not the jazz board
unless he is not programming it right aftwer install
but check your back wall for frost
if you have frost you have an airflow issue
whats happening is the door is being left ajar even a 1/16 gap is an issue
when hot air enters the unit fromn the gap it condenses on the diverter behind the freezer wall
after a few weeks it builds up enought o cause problems
there is a kit you can get that will divert electrical heat to the diverter and keep it warm enough to defrost it there by never having the issue again
Your heading has two model #'s if your dealing with a PBF2253HEW you need a new jazz board pn W10165748 this part also controls your automatic defrost cycles if lights are flickering you should replace prior to something else going wrong
bug, the jazz board is pretty easy to replace. The light cover will slide off toward the back. Now if you look behind the control panel you will see two slots. Take a flat blade screw driver and push the cover tabs in while pulling down on the cover. The cover will come down. Two slats slide in on the front and will release, disconnect the harnesses and install the new board. Reverse the process. Catriver.
