Eoc alam eoc alarm going out when the power is on,what we can check in inverter

dont have anything plugged in when you power it on,if the buzzer still goes off,then you dont have enough power going into it,if it always buzzes,then you damaged the inverter,read more about how inverters work.

The system that you described is a closed-loop system. The inverter tells the motor what to do and the encoder send information back to the inverter to verify the operations.

With out knowing part# and serial number of the unit in question, I do not know exactly which inverter you are having problems with.

With E.OC error, there is a lot of current demand on the inverter. This could mean a short in the motor, motor leads, connections or inside of the inverter. This could also be caused by the encoder feedback loop being defective. If the inverter tells the motor to run at 1000rpm and the feedback tells the inverter it is only running at 5rpm, the inverter will send out more current to get the motor up to speed.

Since you are getting multiple errors, there could be other internal problems with the inverter especially if the unit is old and contaminated internally.

Go to auto zone an test the transmitters battery

For starters first check the wire going to the horn, it may be cut.

Error. Over Current - Peak current exceeded

Possible causes:
Motor has a short - Phase to phase or phase to ground.
Motor cable damaged/defective.
Motor cables too long.
Acceleration/deceleration ramps too short.
Damaged output phase of inverter.
EMI

Check RTD sensor probe andreplace if necessary. If oven is overheating, disconnect power. If ovencontinues to overheat when the power is reapplied, replace EOC. Severeoverheating may require the entire oven to be replaced should damage beextensive

I can only give some general thoughts on this, I have patched up a few inverters.
Their core parts rely on a component called capacitors these over time degrade with heat which reduces their manufactured value this will mean they fail to fully do their job. The usual result is not providing a smooth supply rail allowing voltage spikes which trip over and under voltage sensing firing off the alarm, more so when not loaded with appliances as spikes can become large.
Your appliances would be snubbing out these through their loading but this can be trouble because they are absorbing this extra energy which may damage them eventually.
This situation will possibly get worse with the inverter failing, it will need a service engineer to work on it or to purchase a new one if there is no local regional repair place.
Look up faulty capacitors in power supplies on the web for an insight.

Hope this helps........

E.UP = Under voltage
Check your supply voltage.
E.OC = Over current
Check for shorts between the inverter and motor.

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

test the battery if it is still OK
