LG refrigerator "Er IF" error code is the "Icemaker Fan Error" message.T his error code indicates a problem with the fan that controls the unit's ice production. If this problem occurs because of ice buildup, unplugging the unit for 3 to 4 hours and allowing it to thaw may fix the issue. Call customer service if that doesn't work.

Hi. You may have a bad battery. This can cause lock ups. If it hasn't been replaced in the last 3 to 4 years, take it to a dealer to have the internal battery replaced. The battery will eventually leak all over the inside of the machine and damage it beyond repair. --------------------------------------------------------------------------------------------------
I've had many requests for the Sharp ER-A470 manual. Here is a link http://the-checkout-tech.com/manuals/cashregisters/Sharp6.php

Sounds like it wasn't initialized, even though it says Er 4 instead of Er 0... According to my manual, to (re)initialize it and reset it to zero, tap the platform lightly. It should show zeroes running across the display for a second or two, then show all zeroes and turn off. It should be re-initialized...

Error Codes for the 5757 (according to my manual):

Er 0 Initialization error (remedy described above)

Er 1 Instability error (step off the scale, then back on)

Er 2 Overload warning (registering weight beyond the 440 pound max)

Er 3 Contact error (body impedance beyond technical limit - try dampening feet and try again for better contact)

Er 4 Bodyfat error (bodyfat percentage is beyond range - try dampening feet and try again for better contact)

Er 5 Bodywater error (bodywater percentage is beyond range - try dampening feet and try again for better contact)

CD Changer Error Codes: If problems arise during CD changer operation, the following error codes may appear in the display:

ER-4: Error in the disc unloading function.
ER-5: Error in the magazine position.
ER-6: Error in the laser pickup position.

dear nchase
This problem generally occurs due to the following reasons. I've included the solution too.

1.Windows and air vent wings maybe open .Close windows and vent wings
2.The compressor belt is slipping. Try to Tighten or replace compressor belt
3.Heater is on. Shut heater off
4..Condenser is clogged with debris. Clean the condenser .
5.Refrigerant has escaped through a leak in the system. Have system checked .
6.Receiver/drier is plugged. Have system serviced.

Try these solutions. Do respond with your comments please.
With regrads
Ajuz.

Note: To reset E000, E001, E002, E003, go to service mode 4. select SET, go to "#7 PRINT-ER," in service mode. Then press Execute "#4 PRINTER RESET." Power the unit off/on.
