Power interruption and now my plug,n go seems to be frozen. Cannot set time or clear anything. Screen reads 9.80 or something close

R-9H84B - May 29, 2017

I would suggest pulling the control board out and looking on the foil side (opposite the component side) for "ring cracks," most likely on the low voltage transformer's connections.

The board may have the screen-printed reference designator "T1" near the low voltage transformer.




Also be sure the fuse is not easy to turn with your fingertips when it is in the holder. If it is, the fuse holder is too loose and must be replaced (not just squeezed with pliers).

You can order a fuse holder, part number WB06X10034 for $6.49 (subject to change) from the Pros here.

If you have any keypad issues, please note that the membrane keypads for this model have long been discontinued.

1. unplug the printers power cable it resets ALL printers

2. Once you have it unplug the power cable back in and turn it on make sure it's plugged into the computer.

3. you may need to uninstall and reinstall any software and drivers that came with the printer

4. download and install all the critical updates and service packs for your operating system

5. download and install any updates for your printer from the shap printer driver site

While the set is on, pull the power plug. Then hold and depress the power button in for about a minute. Then replug set and turn it back on. If that does not reset the tv then you do indeed have a serious issue with the set.

check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?



ALSO CHECK THE AIR FLOW VENT SYSTEM and THERMISTORS At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area!


THERMISTORS in the
freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 13000 ( give or take 150 ohms) ohms is required

Printer connected to PC ? No communication between these 2 devices ? Set-up process done properly ? Is this at the office ? Spilled fluid and internal failure ? Jammed paper inside ?

The U2-40 error is the machine telling you that there is a communications error with your CRUM chip.

is there anything at all displayed on the screen??

if there is, press the #, interrupt, C, interrupt in rapid succession. If you don't know what the interrupt button looks like, it is the third button from the right on the control panel. You may have to try it a few times, as with age, the buttons are harder to push so they register that you are pushing them. Once you get into the simulation mode, press 16, then start, and follow the on-screen instructions. once the machine has reset the code, usually shows by going back to the main code screen, then press the CA button, or "clear all".(second button from the right) that will reboot the machine and hopefully clear the code.

Try holding Fn + End with battery and power cord out and while still pressing Fn + End plug only power cable back in and try to power on.

Try turning it off with the power button on the screen, then closing it, then plugging it in... (?) That's what I would do if you havent already.

post your email i will send you the service manual it could be a Thermistor this is what senses the temp and gives the reading back to the control to open or close the damper assby

Go into the diplay properties, under the screen saver tab there is a button marked power, open this. Under one of the tabs there is a section that reads, when I close the lid, under this section set it as never.
