The printed circuit board is a rather expensive item and I would check or have checked the defrost heaters and defrost thermostat first to find if the problem is there. If there is no problem in the heaters or thermostat then go to the next step.

The defrost heaters And defrost thermostat is located behind the rear wall in the freezer compartment. They can be checked with an OHM meter for continuity. The shelving and the rear wall must be removed to access these items.

Why is my Whirlpool s20brsb21 fridge not staying cold ,the temperature seems to vary and food is going off


The most likely fault is the relay on the rear board located behind the back panel , take out the plastic housing that contains the printed circuit board and take the lid off then switch the fridge on and listen for the compressor starting if after 15 minutes it does not start tap the big orange relay with a the handle of a screwdriver if the compressor starts you need to change the relay and associated capacitors, if that is not possible just change the complete board.
there are loads of other possibilities but that is the most likley

Whered can I purchase a printed circuit board for 8203 series spa and what is the cost?


OH is the Over-Heat event code. Not likely related to the board, this comes up for a number of reasons -
Flow issues cause the heater tube to get too hot. Dirty filter, suction blockage, low water level etc...
Hi Limit sensor has failed or the temperature sensor reading incorrectly.
Usually its a flow related problem

Tt18hpxlt defrost timer


there is no defrost timer in this model,it is called an A.D.C. adaptive defrost control and is located in the refrige compartment just above and behind the cold control setting inside this plastic case,remove this case from the top of the refrigerator compartment and you will see a small printed circuit board,this is the A.D.C.

Jenn-Air not cooling. Repairman replaced 'defrost control board.' Still not cooling. Control to set temperature will not move from zero. Any suggestions appreciated.


Generally when a printed circuit board faults it often takes out the other boards too.
You may need to get the main PCboard replaced too

Hello,

When the refrigerator side is getting too cold this is because the control of the compressor has gone bad in some way...

There a few different things that could cause the unit to lose control over the temperature of the fridge side.

If your refrigerator has a damper door that opens and closes to allow cold air to move to the fridge side the damper linkage or the damper motor may have broken or gone bad.

The coils in your fridge may have frozen over and now the air does not move at all so then the ice builds up and can freeze parts of the fridge side.

The thermostat has gone bad and so now the compressor runs continually. This will not be noticed readily on the freezer side but will show up quickly on the fridge side.

Many newer model refrigerators use an electronic sensor or thermistor to read the temperature and supply the info for the circuit board and often a digital readout.

So, here is how I would go about troubleshooting this problem.

Check the coils for ice, defrost the coils with a heat gun or hairdryer, then check for the reason why they iced over. Defrost control or defrost timer bad? Evaporator fan bad?

Check the damper door to see if it is stuck in the open position. If it is then check the motor and the linkage.

Check to see if the refrigeration unit will shut down if the thermostat or digital setting is turned up to a higher temperature. If it continues to run then find the cause and fix it. It may be a bad thermostat, sensor, or control board.

Sometimes with a change is weather to a cooler climate this will be enough to also affect the inside temperatures. Make sure that a bit of adjustment in the thermostat or setting of the temperature will not solve your problem very simply.

I hope the above helps.

Good luck.

DO NOT TRY TO MODIFY TIMING CYCLE.you would need to completely modify printed circuit board and inbuilt computer......some freezers cycle around 6 to 8 hours.the temperature can only be checked say every 12 hours to get an average reading
