My true freezer temperature gage has a P1 flashing code

My true freezer temperature gage is flashing a P1 code one moment and then it reads 125-230 degree next but is actually freezing fine. All we did was change the solenoid. What do we need to do? thanks

If unit keeps proper temp. then I would think that either the thermometer sensing probe may have been damaged during the repair process or the thermometer itself has failed.

Freezer losing temperature


Hi Julie. I'm Roger. It sounds like the operating thermostat is not working When not in the fast freeze mode. Can you here a click sound from the thermostat when turning the temperature up and down short of fast freeze? We normally charge them to operate at -10 to -20 degrees. The inside temperature will normally only reach a temperature around 18 degrees warmer. The operating thermostat should allow you to regulate its temperature any where from that capability up to where you want it. See if your thermostat makes a clicking sound when adjusted. The warning light comes on because it knows the box temperature is higher than it is set for and is warning you of that. If it uses a printed circuit (PC) board, the click will dot be very loud. listen closely. Let us know how this turns out for you. We have very good refrigeration techs. here. Someone else here may have an idea too.

When the defrost comes on it is on to long the temp gets above freezing I need to make the defrost cycle shorter


Does it? Or is it just the display that reads 50? Don't forget the evaporator has to get to 50f to get rid of the ice forming on it. It will do this 3 or 4 times a day, but the product temperature should not creep much above setpoint. Check the food temperature with a digital probe when defrost occurs to see if it is only the display module ( which may have it's sensing phial too close to the evaporator or have lost it's insulation jacket)
Also check the grill in the base (condenser) is clear and clean so it recovers from defrost as it should..

P-1 code is flashing on temperature display


P1 is almost always a fault on the sensing (control) probe. Check it's end is not wet or covered in thick ice, and check the connections at the controller. If you can, change the probe connections on the controller temporarily. If P2 then shows it proves the probe is faulty. If P1 still shows, it proves the controller is at fault.

What shld settings be as food is freezing in fridge it has side by side knobs saying colder mid less cold it is a westinghouse fan forced frost free freestyle unit


The settings are "relative". Someone with this fridge in Montana may need to run the same fridge with different settings than someone in Texas to get the same temperatures.

Many manufacturers recommend that the fresh food compartment should be 34 degrees F, and the freezer -10 to 0 degrees F. To set this properly, place a thermometer in the freezer (that can display temperatures as low as the desired temperature). Adjust the thermometer for the correct freezer temperature before going on to the fridge. A fully stocked freezer could take 12 hours or more for temperatures to stabilize after making changes to the thermostat. Once the -10 to 0 degree temperature has been achieved, set the fresh food compartment temperature.

Place a thermometer (that can display below freezing) in a 6 (or so) oz flexible plastic cup of water and place on a shelf in the fridge. A glass of water could break if the temperature gets below 32 degrees if the water turns to ice. The water acts as a buffer to rapidly changing temperatures when the door is opened to read the thermometer. If the fridge is "full", allow 24 hours for the temperature to stabilize before making changes.

If the fridge and freezer are empty, changes may be seen in just a few hours or less. Otherwise, wait the 12 / 24 hours for the freezer / fridge compartments.

I hope this helps and good luck!

Freezer is around 3 years old. When set at -17 degrees the freezer clicks very noisely, a relay operating I think. When the fast freeze button is pressed this clicking stops but the display reads -27...


In my opinion, since your going for the fast freeze mode, your freezer sets to its lowest operating temperature to fast tract the freezing process.

and about the noisy clicking sound it is probably a thermostat or relays depending on your system which starts and stop the compressor.

i think your freezer is just doing fine.

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

TRUE freezer model number GDM-49F.


Your unit should have a defrost timer.The timer may be stuck in a defrost.It should be located at the bottom of the unit next to the compressor.Open the door to the timer and observe the position of the timer.If you turn the knob and the unit starts up,it's the timer. If this is the case, you can purchase a new one at any local a/c supply.Let me know,Mike
