What is Code p2 on a Kenmore electric dryer?


error code indicates that the electronic control board detects an open thermistor (temperature sensor). This is usually caused by a failed thermistor. It can also be caused by a wiring problem or a failed control board.

To troubleshoot this problem, follow these steps:

Unplug the dryer to completely disconnect electrical power. Shut off the gas supply.

Remove the bottom front service panel as shown in the first image below.

Locate the thermistor on the blower housing. The second image below shows the thermistor. It should have a red/white and a black wire attached to it. Pull at least one wire off and measure the resistance across the leads of the thermistor using a volt/ohm meter. You should measure about 10K ohms (10,000 ohms) of resistance at room temperature. If you measure infinite resistance or get much different reading, then the thermistor will need to be replaced. Even if the thermistor reads the correct resistance at room temperature, it could still be defective and giving a bad resistance reading at higher temperatures.

If you suspect that the thermistor is good, check the wiring connection at the main control board (black and red/black wires on the P2 connector). The procedure for accessing the control board is shown in the third image below. With the dryer still unplugged, pull the P2 connector (see diagram of board) and check the resistance through the black and red/white wires. NOTE: The wires down below at the thermistor must be properly attached back onto the thermistor to properly check this circuit. If you get a much higher resistance (or infinite resitance indicating an open circuit) when measuring this circuit from the wires at the control board, then you could have a wiring failure that is causing your problem. If the resistance is the same, I recommend replacing the thermistor and testing the dryer to see if it operates properly.

If you still get the error code after changing the thermistor, then the control board will need to be replaced.

My microwave says "SE" or "5E" and won't work. What does this mean?


The problem lies with the mylar ribbon cable that connects the Keypad to the circuit board. The Mylar ribbon cable folds back onto itself and are touching. Over time the mylar 'breaks down' electrically and the wire traces in the mylar will 'arc' onto the other mylar ribbon cable. The solution is to separate the two mylar ribbon cables using paper and electrical tape. I've done this on several microwaves (not just Samsung) and it has worked every time. Patience and about 20 minutes is all it should take to fix it. I've described below how I did it for the SMH9187ST Microwave Good luck to all.

1. UNPLUG THE MICROWAVE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

2. 1. Remove the top front cover by removing the (2) screws that are along the top edge (phillips).

3. 2. Slide the cover to the left about a half inch (there are tabs holding the cover in place) and remove.

4. 3. Remove (1) screw from the top of the Keypad Housing (phillips). Lift the Keypad Housing upwards about half an inch (there are tabs holding the Keypad Housing in place) and remove. Be careful of the metal grille that is just above the Keypad Housing as this may fall out since it is being held in place by the Housing.

5. 4. Be careful not to pull on the wiring harnesses that are attached to the Housing. Carefully unplug the wiring harness that has the RED connector on it from the circuit board. Carefully unplug the small white connector that has the mylar ribbon cable on it (this cable is see-through and you can see thin, flat wires in it).

6. 5. Remove (4) screws that are holding the circuit board onto the Housing.

7. The Housing should now be free of the circuit board and wiring harnesses. It's safe to let the wiring harness/circuit board hang free, but caution should be used anyway.

8. 6. Remove the thin metal frame from the Housing. There are (4) plastic tabs holding the frame in place. Using a small screw driver pry one side of the frame away from the housing (try to do this to the side that has smaller plastic tabs). When this side of the frame is free of the Housing you have to lift the frame out at an angle to remove. It might put up a fuss, but be patient and be gentle with it since the frame is thin and fragile.

9. 7. With the frame out of the way you will see the mylar ribbon cable that is coming out from underneath the Keypad assembly. You will notice that the mylar ribbon cable folds back onto itself as it re-enters the Keypad assembly. This 'touching of the two ribbon cables' is where the trouble lies. The ribbon cables may be stuck together. Carefully separate these two and then insert a small piece of paper between them (paper can be 1/2 x 1/2 ) and work the paper all the way down into the Keypad assembly as far as it will go.

10. 8. Using electrical tape, apply a small piece between the ribbon cables to hold the paper in place. Next, use more electrical tape and put it between the mylar ribbon cables enough so as to keep the ribbon cables separated.

11. 9. Re-attached the thin metal frame making sure to press it into the Keypad assembly enough so that the (4) tabs click into place.

12. 10. Use electrical tape and apply it to the raw metal edge of the thin metal frame to prevent the mylar ribbon cables from rubbing on the metal edge.

13. 11. That's it. A final word of caution. Be careful when inserting the ribbon cable connector back on to the circuit board. The connector is loose and you need to gently place the ribbon cable into the circuit board connector.

14. 12. Reverse the order of assembly from above.

15. 13. Plug in the microwave and then it should reset and ask you to set the time.

Best of luck to you

My nokia model no 7230 fell in water after that every time the mobile turn on but after that no key works.


If you open your cellphone after falling it to water,its possible to damage the keypad circuit because of shorted happened in the circuit board when it fell, so better to look for a cellphone technician to troubleshoot it to avoid major problems.

My smh model is less than a year old -SE- appears on the display screen does this mean the keypad needs to be changed?


If memory serves me, -SE- means system error which indicates a keypad failure, the microprocessor ic is mounted on a circuit board along with other componants directly behind the keypad and controls the oven vital functions. If you have any warranty of any kind, now is the time to use it.

Rotate the iTrip AutoPilot FM Transmitter controller so that its buttons are facing up and its data cable is on the left side. The data cable wires attach to a row of contact points along the left side of the circuit board as follows (from top to bottom):

1 = Purple
2 = White
3 = Blue
4 = Red
5 = Black
6 = Brown
7 = Green

BM - After Self-Clean Problem -- 30


Brain, check your thermal fuse first. You can do this at the board. lower oven, p26-2 orange or p26-4 red wire to red wire at the terminal block. Should show closed circuit. Upper oven, p18-4 red or p18-1 red to red wire at terminal block. Should read closed circuit. If open, there is your problem. Control transformer is as follows, primary windings, P16-5 red to p16-7 red, 75 to 95 ohms. Secondary windings, p16-2 blue to p16-3 blue , 2 to 4 ohms. I do believe your problem is in the thermal fuse on the back. Post back, Catriver
