If C = 3,9 nF
L = 5,3 mH

f= 1/6,28/sqrt(L*C) = 220 Khz

If you had problem with this solution, you could give additional question.

My Frigidaire electrolux dishwasher model # FDB2310LCC0 trips a pf code 40minutes into the cycle and it is not the circuit breaker. how do i correct this problem?


Good Morning Doria, thank you for allowing me to assist you!

Typically PF means power failure and you should be able to start a cycle. Unplug the unit or flip the household circuit breaker. Wait about ten minutes and then turn the unit back on. If the error code continues to display, I would suggest contacting a professional to accurately diagnose and repair it.

Best of luck!

Sorry I do not speak English well. C120 pac my team. PF mark on the screen and turn on all lights. not working I have to do Thanks for your time


This unit stopped working and displayed the PF code for Probe Failure. I fixed it by removing 6 screws for the panal and 4 screws for the back panal and removing the 5 screws and 1 screw holding the ground wire off the silver box with the circuit board in it then I un plugged the little plug for the 2 probes with the black wires in it and replugged it in and wiggled it several times with the unit pluged in (be carefull not to get shocked I recomend someone with electrical experiance do this for you) the plug must get corroded but this fixed my unit.

Good luck.

I have generac c 5000 series, that is 5000 watts . can you give me the equivalent watts given into Kva?


philliprabay,

This is the formula The conversion of W to KVA is governed by the equation KVA=W/(1000*PF)


For example 1500W/(1000*0.83) = 1.8 kVA (assuming a power factor of 0.83)
Thanks for using FixYa and for the great rating.

The initials "pf" come on and prevent our fridgidaire dishwasher from continuing it's cycle. What is the problem?


"PF" generally means Power Failure. First, be sure that the door is latched tightly. Vibration may loosen the latch causing the unit to stop. Also check your circuit breaker. Flip it to the "tripped" position and firmly back to the "on" position.

If this model is an "electronic" unit (for example uses a touch pad for programming), there may be a loose connection somewhere in the wiring prior to or at the junction box under the dishwasher. The electric "noise" generated there might confuse the dishwasher's computer. Best to have an electrician look at this.

Dryer won't turn on


Using a resistance meter, check the resistance of the motor that turns the dryer. If it short circuit (0 ohms) or open circuit (50ohms or greater) then you'll need a new motor.

There may also be a open circuit to the motor than inhibits it from functioning correctly.

An appliance serviceperson should be able to troubleshoot the motor and any other circuit faults. Perhaps a new (or slightly used) dryer is the cheapest solution.
