E.up and eoc always occurs,what the problem? - Inverter KEB COMBIVERT F5

E.OC is an over current error.

The inverter is sensing a short on the U/V/W terminals. This could be a shorted motor, motor leads and an internal short in the inverter.

Disconnect the motor leads from the inverter, and run the inverter as you normally would.

If the E.OC error does not occur the short is external of the inverter.
If the E.OC occurs, then the short is internal to the inverter.

Hello Bill Robbins - From what you are describing it sounds like a wiring failure or a communication break failure between the power board and UIB has occurred. Error code F5, typically indicates that the EOC will need replacing. A certified technician will need to test the wiring harness between the ESC, UIB and EOC.

Depending on the serial cable you have, you may need a modem (crossover) adapter between the cable and the EOC-3220. A good diagnostic is the following: with the EOC-3220 unplugged from power, connect your serial cable and make all the proper baud rate etc. settings in your serial communications program. When it is running, plug the EOC-3220 into power. If you don't see any garbage characters appear on your screen when you plug the power in, your comm program is probably not set up properly. If you see garbage characters but they are not immediately followed by good information from the EOC-3220, then you either need a null modem adapter inline, or you have a dead EOC-3220. If you've never communicated successfully with an EOC-3220 before over the serial channel, the only way to know if you have a dead one is to try again with a known-good one.

Assuming you are using the proper serial channel reset procedure, this should not be occurring. If it is occurring, your unit is probably malfunctioning and cannot be corrected.

Hello, I come across this problem quite often, The f1 error code does not always follow that it is a bad EOC (Electronic oven control) This could also be a problem with the touchpad. The way to figure which is bad is turn electric off, access the EOC and pull the wire harness/ribbon tape for the touch pad. Reassemble the range and switch power back on. If you are still getting the F1 it is the EOC..If the F1 clears then your problem is with the Touchpad. If you have any other questions please feel free to comment again. Good Luck!!! Mike

Dear Venmattey,
please follow these steps, it works:

1. Connect the EOC-3610 to your computer with a null modem serial cable.

2.Start a HyperTerminal session: Click Start and then select Programs-> Accessories -> Communications -> HyperTerminal.

3. After the HyperTerminal window appears:
a. Give this new connection a name. Ex: EOC-3610.
b. Select correct COM port. Ex:COM1.
c.Set baud rate as "38400", data bits "8", parity "none", stop bits "1",and flow control as "None". Then press “OK” to bring up theHyperTerminal window.
d. Unplug the power on the POE injector and wait 5 seconds then plug the power back in.

4. Wait until the "#" is displayed in the HyperTerminal window.

5. Type "flash reset", then hit enter.

6. Type "reboot", then hit enter. After the device reboots, all settings will be at factory default.

NEW: Keenan Systems has written a software that will soft reset the 3610 series back to factory reset. Thisfree software is provided "AS IS" by Keenan Systems and is notsupported or guaranteed by EnGenius Technologies. Use at your own risk.

Be Happy Always

well first it doesn't matter when the problem occurred warranty is warranty but you can pull the oven out and pull the panel off the top where the eoc is and pull the mylar ribbon out there is a black plastic piece at the base of the ribbon pull it up and pull the ribbon out clean it with a pencil eraser then reseat it and lock it down if that doesn't fix it then the eoc must be replaced go to www.frigidaire.com and find a service in your area it will be a warranty issue
