Haier Condenser gives an error: F9.

Hi Navin, The link below is a Air conditioner error codes manual, Good luck and CHEERS..
F9 light
discharge temp. sensor of compressor fault
1? Check whether the resistance of sensor is normal, otherwise replace it.
2?Check whether the sensor wire is short circuit or open circuit, and whether the plug is well contacted, whether there is welding off or rosin joint on the electric control 9 board, repair it if there is any above.
3?When the 1 and 2 are both normal, then the components or integrated circuit is damaged, the electric control board should be replaced.

Error 1 is a defect in the steam heating unit.
Possible solutions:
Thermal sensor is defective -replace.
Cable to the thermal is broken or contact pins are corroded - replace, repair.
Heating or thermal cut-out are defective - measure and replace parts if required.
Triac on the power board is defective. The heater heats up triggering the overtemperature protection - Replace the overtempereature protection (thermal cut out) and the power board or the single triac.

E004
The main thermistor (TH1) has an open circuit or has poor contact. The sub thermistor (TH2) has an open circuit or
has poor contact. The thermal switch (TGP1) has an open circuit. The main heater (H1)/sub heater (H2) has an open
circuit. The AC driver PCB is faulty. The DC controller PCB is faulty.

E004 0001 protection circuit error of the fixing unit

Description: A short-circuit is detected in the triac (for 1 sec or more continuously) while the heater remains off (hardware detection) for 40 msec continuously.

Remedy: Turn off and then on the main power supply.

Remarks: fixing assembly triac malfunction/13V power supply error

P0137 Error code Faulty O2 sensor Exhaust leak near the rear sensor

• Plugged catalyst
• Short to voltage on O2 signal circuit
• High resistance or open on O2 signal circuit
  

Possible Solutions

• Replace faulty sensor
• Repair exhaust leak near the rear sensor
• Check for restriction in catalyst and replace as necessary
• Repair short, open, or high resistance on o2 signal circuit

P0141 Error code means Downstr Heated Oxygen Sensor Heater circuit fault - Bank No. 1.

- replacement is needed for this issue.

P0342 Error code means Camshaft Position Sensor Circuit Low Input

P1792 Error code means P1792 means the computer isnt properly programmed so if this code keeps comming back the pcm may need to be replaced

Depending on the machine
F9: MOTOR FAULTS - the common cause of this is just worn out motor brushes. The other causes of an F9 error are TACHOMETER short or open circuit, motor short or open circuit, or motor jammed.

You have a faulty keypad. You could probably special order this part from a local appliance parts supply store for 50-60$ or purchase a new microwave.

Open heat error, you have a fuser problem, replace fuser. Fuser consists of Upperheat roller, lower heat roller, exit claws/rollers, and a heating circuit with a lamp, thermal temp sensor (thermistor) and a thermal fuse/cutout.

You could measuring fuser removed from machine, checking lamp etc for open circuit, thermistor should be neither short or open circuit.

These days we dont, we just change assembly due to it being a common constantly wearing part, and if for example I pull it apart, fix the lamp, put it together then soon enough I will need to pull it apart again to fix worn roller etc.

I could give you the part number ... JC81-01690A but dont use it, cause that part is for 220volt cause thats what we use in Oz, so contact Samsung and ask for dealer in your country who can supply you.

P.S. Fuser is the Hot bit (180 deg c) at back near paper exit that bonds(melts) the print into the paper.
