Kenmore elite model #253.4451360 flashing error code EF can you tell me the issue the refrigerator will not operate and cool

first disconnect power to the unit. remove the bottom grill and now remove the screw holding the main board and pull the main control board out from under front of refrigerator.. when you have access to the board, reconnect power to the unit. you will need a meter that reads dc voltage to make the following checks. be very careful when making these voltage checks. locate the j2 connection (see picture) and place the leads on j2-3 the brn/wh wire and j2-5 the rd/wh wire. do not disconnect any of the wire connections. there should be 12vdc there. if the voltage is not there, the board # 241511101 will need to be replaced. if the voltage is there, leave the lead on j2-3 and place the other lead on j2-10 the bl/wh wire and it should read from 6 to 12 vdc. if there is no voltage there, again replace the board. if the voltage is at both places, the motor will need to be checked. to access the motor, everything in the freezer will need to be taken out, so the back panel can be removed. first disconnect power to the unit. with the panel out, you will have access to the motor. first check the connections. if they seem ok, reconnect the power and now make the same voltage checks that were made at the board. again do not disconnect any of the wires. all wires must be in place when making these voltage checks. if the voltage is there and it's not running, the motor # 241509402 will need to be replaced

Mitsubishi City Multi VRV unit fault code 2502

2502 code indicates float switch issue. Try taking a wet vac to the outlet of the drain line and cleaning it by vacuuming the outlet. This will clear the drain line if it's not tied in with multiple drains, but may not clear the code. To clear, try tuning off breaker(s), wait 10 mins, then turning breakers back on. If this doesn't help then there is an issue with the float switch or the control board. Float switch is supposed to prevent the drain from over flowing and is normally located in the condensate pan, but I don't advise anything else, other than cleaning the drain line and resetting the system.

Daikin VRV J2

This is a fault with one of the standard compressor’s current sensors.
It occurs when the units PCB asks the compressor to run but then doesn’t recognise that the compressor is drawing any current. This can be due to a fault with the compressor contactor not coming in or a fault with either the Main PCB not giving an output to the contactor or not receiving the signal from the current sensor, or it could be a fault with the current sensor itself.

Drum Cartridge XE Series P8 part number 13R553 Printer code J2

With "J2" flashing, press:
1. "CLEAR" button
2. "AUTO" button, then again
3. "CLEAR" button
4. "AUTO" button

Do it fairly quickly. If it's done quickly enough the display goes off. When it does:
5. enter "2" and "4" (see "24" on display)
6. Press "START/COPY"
7. Press "7"
8. Press "START/COPY"

If display doesn't go off repeat steps 1 to 4 but faster, until display is off.
