H4 flashing on Sharp copiers indicates that the fuser tempurature has failed to reach temperature in a given time. The posible causes of this are 1.Failure of the heater lamp or heater lamp drive circuit. 2. Failure of the temperature sensing circuit. 3. The initial temp. of the fuser roller was very cold. or 4.low mians supply voltage for a short time (brown out). The copier does not allow a simple on/off reset of this fault because in cause 2. above the copier may overheat and cause a fire.
The reset for this model should be:
Clear ® Density select ® Clear ® Density select - 14-Print.

The check engine light keeps coming on and off while i ride im smelling a burning smell what could be the problem ?


Beings the "Check Engine Light" goes off and on, there SHOULD be one or more error codes stored in the system.
Have you tried pulling any error codes?

The speedometer is capable of displaying & clearing speedometer , tachometer TSM/TSSM , HFSM , ECM , ABS Diagnostic Trouble Codes also known as DTC's.
1 - Turn the ignition switch to off & run/stop switch is to run .
2 - Push odometer reset button in & HOLD .
3 - Turn the ignition switch on and then release odometer reset button . The background lighting should illuminate & the speedometer needle should sweep it's full range & indicator lamps ( battery , security , low fuel , check engine and cruise ) should illuminate . The word "DIAG" should then appear .
4 - Push the odometer reset button once and you will see the selection menu "PSSPtb" with the first P flashing .
5 - Each letter represents a area of the diagnostics module . The module that is flashing is the one you are going to check . To move from one letter to the next you must push the odometer reset button one time . ( from P to S to SP to t to b and back to P , ect ect )
P = ECM
S = TSM/TSSM/HFSM
SP = speedometer
t = tachometer
b = ABS codes
6 - To get the DTC code in a area of diagnostics you should PUSH & HOLD the odometer reset button in for 5 seconds and the release . If there are any DTC's the code will be displayed or the word " none " will appear if there are no DTC's . Push the odometer reset button again to view any additional codes if they exist .
7 - Record the codes .
8 - If DTC's are NOT to be cleared , press and release the odometer reset button . Part #of module will be displayed .
9 - If DTC's are to be cleared for that module , PRESS & HOLD the odometer reset button until " clear " is displayed .
10 - Press and release the odometer reset button to continue to the next module .
11 - Turn the ignition switch off to exit the diagnostic mode .


If you DO get any error codes, repost them for diagnosis.

FOR GENIE GARAGE DOOR OPENER ICA SERIES WITH INTELLICODE REMOTE CONTROL SERIES II ELECTRONICS. PROGRAMED REMOTE FOR NEIGHBORS DOOR, WHRN NO LONGER NEEDED THE ACCESS I RE-PROGRAMED TO MY DOOR. NOW BOTH...


First you want to clear both Garage Door Openers. To clear the openers you need to locate the learn code button. This button is (usually) under the white lens cover just push it and hold it in until the red light stops flashing then do the same thing to your other opener. This clears out all remote controls that are programmed to these openers. Try the remote to make sure the units were properly cleared. Neither opener should activate if this was done correctly. After units are properly cleared push the learn code button on the opener that you want this remote to open. The learn code led will flash, then press the button on the remote once (learn code goes solid), press the remote a second time ( learn code goes out). Press the remote a 3rd time and opener should activate.

F1 flashing on gas stove-manual says to push clear-where is clear button


HI. This actual code cannot be cleared by pushing the Clear/off button. This actual button will usually be located on the touch pad and is a basic cancel button. You can try to reset the entire control board by simply unplugging the unit for 5 minutes. This may correct the issue. If resetting dose not correct this fault, the necessary actions are to have the defective main PCB replaced, asap.

F1 - Defective control board(PCB)

UNDERNEATH THE TRAY WHERE THE PAPER COMES OUT THERE IS A ROTORY SWITCH WHICH IS CLEAR IN COLOR. IT IS EXTERNAL. IT MAY HAVE BEEN TURNED SLIGHTLY. IT IS SOME SORT OF LOCK, THAT IS WHY THE L IS FLASHING. IT IS RIGHT UNDER WHERE THE PAPER COMES OUT OF THE PRINTER. AFTER YOU TURN IT IN THE STRAIGHT POSITION, PUSH THE CLEAR BUTTON THEN THE BUTTON JUST LEFT OF THE CONTRAST ADJUSTMENT BUTTONS. DO THAT TWICE IN A ROW AND THE PRINTER WILL TURN OFF. PUSH CLEAR AGAIN AND IT WILL TURN IT BACK ON AND ALSO CLEAR THE TROUBLE CODE. GOOD LUCK.

Error code on electrolux


Haven't tried your solution but I'm keeping it in mind. I talked to a repairman and he suggested I remove the panel at the bottom of the dishwasher (left side). There I will see a red button which is the control board processor reset button.

This worked but if the problem reoccurs I will try your solution as it is easier than removing a panel.
