Transformer burning in power board ( model # plef398cca )

I checked an electric range Model # PLEF398CCA ( FRIGIDAIRE )
Found power board's transformer burned out, I check range could not find any other problem. After installing a new board, It burned out again within two minutes. I recheck most basic components again I could not find any other problem. What am I missing? can you help me?
Thanks Jose Cano from Florida.

Vahid, is the display black, nothing there? Try pressing the bake and broil pads together for 3 seconds until display shows SF. Then press clock. If this doesn't work try the ERC test by doing this; Kill the power to the range for 10 seconds. Press the cooking time, delay start and number 8 pads all together. The display should show the word test. Give this a shot back.

SOURCE: Range goes into lock out mode

I have experienced this with a Maytag model before. What I was told by the technical assistance folks, is that fluctuations in power coming from the line voltage being fed into the home, electrical storms, or even ham radio (high power RF) operating in the area, can cause some electronics to appear to have problems when they don't. The theory is that these circuit boards are so sensitive that even the slightest noise or interference on the line voltage coming in can cause the board to go into a lock out mode. I was able to clear the problem I had by resetting the computer. There is an actual procedure for this if you haven't figured that out already. If you haven't figured out how to reset the unit, you may need to call the technical support department for your model to see if they can provide you with better answers. I hope this sheds some light on this problem for you.

SOURCE: instructions for frigidaire oven

an f1 one code means that
Electronic control has detected a fault condition. Turn the Temperature Control Knob to
OFF, and disconnect the power to the range. Wait 30 seconds and reconnect the power.
If fault recurs, disconnect the power and contact an authorized servicer.
You can get all the codes here in the manual.

SOURCE: Frigidaire Classic Range, Model # FEF366CCB, F1 error

Here is some wisdom for understanding F1 fault codes.

In some models, there are subcodes that make diagnosis even easier.

Here's a simple explanation of what's going on and how to troubleshoot:

The F1 code indicates that:

a. The electronic range control (ERC) is sensing heat in the oven when in a time-of-day (i.e., not cooking) mode.

b. The ERC is receiving information to run multiple heat functions simultaneously.

Although different components (depending upon the model) could generate the code, simple and straightforward testing using your ohm meter is all you gotta do to test for it.

1. Check the oven temperature sensor. The oven sensor has to be within spec or it will cause the F1 code.
As an example of being out-of-spec, the ERC will generate an F1 fault code when the sensor shows 1650 ohms during a time-of-day mode.
This is equivalent to 350°F in the oven.
The resistance isn't high enough to generate an F2 code (runaway temp) or an F3 or F4 code (shorted/open sensor circuit).
The ERC monitors the sensor circuit after a heat cycle and expects the resistance to drop back to 1050-1100 ohms.
The fault code is generated when this doesn't happen. Checking the sensor circuit means also checking the harness,
harness connections and the sensor itself.

2. If the oven sensor circuit checks okay, then turn your inquisitive eyeballs to the touchpad.
If the range has a separate touchpad/keyboard, the keypad may have moisture that is shorting several circuits simultaneously.
If the F1 code is given immediately (instead of during or after a heat cycle),
remove the ribbon connector from the touchpad to the ERC after clearing the F1 code. If the F1 code does not return in five minutes,
then cast a suspicious gaze upon the touchpad/keyboard. Shorts may be caused by using an ammonia-based glass cleaner.
The touchpad surface will absorb ammonia-based cleaners that are sprayed directly on the glass surface. When heat is applied,
the surface material can break down causing shorts.
If you're gonna use ammonia-based cleaners on your control panel, then you should spray it on the rag and then wipe the touchpanel
-don't spray directly onto the surface of the touchpad.

3. On Amana ranges with a rotary temperature dial, be sure that the knob is in the OFF position when performing tests.

4. If these tests all check good, then replace the ERC.

Electric element burns high even on medium setting. Replaced entire element and still having the same problem FRIGIDAIRE STOVE , SN VF23145789 MODEL FFEF3016LWF

Hello Charles, thank you for your submission!
I understand that the element on your Frigidaire range burns high on a medium setting and it has been recently replaced. This could be a possible problem with the wiring harness or switch inside of the range. Since it could be anyone of these underlying issues I would strongly recommend having a professional technician out. This will help you avoid any unnecessary part purchases. Hopefully this information can be helpful towards your repair. -Matt

Bought a replacement control board for frididaire oven but it doesn't hook up with power strip but it looks like I can jump it but how

Hello friend, thank you for your post!
From my understanding you have a replacement control board for your Frigidaire range and the power strip doesn't hook up properly so you would like to jump it over. I would not recommend doing so because you would be unsure what kind of electrical miscommunication that could cause. The part you have ordered maybe incorrect. If you can provide me with your model number I can double check your parts manual. You can locate your model number on the door frame of the lower drawer. I look forward to assisting you. -Matt

I own FRIGIDAIRE ES100/105 (electric stove and oven). Yesterday I was using the oven and suddenly I heard a loud sound. I went to check it I found out the both the oven and stove were off. And not working....

HI. The actual issue will be with the main logic board, which is where the main element control relays are mounted. These very important relays are damaged. The main board will need to be replaced, asap.

With that said, if you could be so kind; Please post the entire model number so that i may pull up all necessary part numbers needed, as well as, service manual links and diagrams to help with your repair.

check to see if the unit has 240 volts going to the unit if it does take the back off after removing the power look for a black or burnt spot at the wire connection and on the control board repair or replace that wire or component

My Frigidaire range display has gone out and the oven doesn't work.

sun, first test is to power the unit down. Find the pair of breakers which are generally 40 or more amperes. Turn them both off and back on. If this doesn't fix it, you will probably need a circuit board.
