The E/F error code is indicating a problem with the evaporator fan motor inside the freezer. It could be caused by a failed fan motor, control board or a loose wiring connection between the two components. The control board monitors the evaporator fan motor operation and speed. If the control board does not receive information from the fan motor or receives incorrect information because the fan motor has stalled out or is not running correctly "E/F" will display.
This type of error code will require a service technician in order to diagnose the failure. I recommend calling a service technician to repair your refrigerator.
fully charge your heli----turn on transmitter-wait 2 seconds-turn on heli wait for blinking green led to stop blinking-turns steady.....rev up with a quick full throttle and back to idle--happy flying
My helicopter charged once worked and flew once for about 5 minutes. Then the helicopter stopped responding to the controller and it wouldn't take a charge. When I connected the remote to the helicopter the CHG light came on solid for about 30 seconds. This means that the controller is waiting to be plugged into the helicopter.
A couple of points to check before you go further: 1) make sure that the helicopter is turned OFF before charging! 2) When charging the red CHG light will blink. 3) When finished charging the red CHG light and the green Power light will blink at the same time. 4) After a certain amount of time both lights will stop blinking to save the batteries.
After taking the helicopter apart this is what I have found: *The helicopter has a 140mA-H 3.7V Li-Po battery. *The battery has a little board with 2 tiny computer chips. When the battery is empty these 2 chips will completely disconnect the battery. This prevents damaging the battery and this is why the helicopter stops responding when the battery is empty. *There are two connections between the battery and the little board - a long connection which wraps one time around the battery and a short connection. My problem was with the short battery connection.
Solution --The little board has a short piece of foil which connects to another short piece of foil on the battery. These two pieces of foil are simply pressed together and then glued. In my case this connection broke. To fix the problem I removed the yellow tape and glue and used a soldering iron to solder the 2 foil pieces together. Make sure that you put tape (any household tape should be OK) back on the battery to prevent any shorts.
OK, this is a failed controller board, any E4* is Power supply & Controller Board, probably caused by a power spike.You need to get the unit looked at to see if it is able to be repaired, and if parts are available. If you wish to try and repair this yourself, you must get a service manual, to do so, and to be able to order parts.
Your icemaker sensor is out of its place. unplug the unit . check bottom of your icemake, the sensor looks like a little ***** , insert it back. turn unit on, and reset the board, Hold power freez, Power Cool for about 10 seconds.
You might have part of the answer in your own question - You would need to have it serviced - most likely the control board / electronic controls that has gone bad - this board controls compressor cycling and other functions of your refrigerator. Look for any error messages or blinking lights or a red service light if any - you could try unplugging your refrigerator for a few minutes and plug it in again if you are lucky and things reset otherwise have it checked. There is nothing much you can do on your own here without knowledge on the parts and how to locate it.
Other than control boards, if your compressor IS running but cooling takes a long time then check the condensers at the back if they are dirty, you need to keep those dust free and clean them about once or twice a year - warm, no cool, compressor running, I would then check for low refrigerant / leaks in the system (although rare). Most common problems affectin refrigerators are defrost timer problems, relays and controll boards going bad
