Unit: Frigidaire upright freezer FFU14F5HWB Symptom: 1. Ice buildup in drain tray. Ice has been removed. 2. Temp stays at -19 deg. F regardless of temp setting compressor runs constantly & red alarm light on. Trouble shooting: 3. Compressor good, coils cold, outside side-walls get warm, heater good 30 ohm resistance, heater thermostat good continuity, fan starts 1-2 seconds after plugin, unit is level & door seals are OK. 4. I suspect Thermistor Part Number: AP3780724, MFG P/N 297018400 may be the problem. 5. What is the correct resistance in Ohms of the above thermistor at 32F (+-5% in a cup of ice water for 5 minutes)? It might be helpful to note that after warming the unit for several hours, restarting it & running it overnight the alarm light eventually clears and the temp settles at +2F. After 1 or 2 days the alarm comes back on and the temp is down again to -19F. Perhaps this indicates an intermittent failure of the thermistor or else it is just that the main board program requires a time delay or a number of occurrences before showing the failure alarm. So while I order the new thermistor I will be watching for a repeat of this failure cycle. Thanks for your advice,

Compressor runs (and it checks out for ohms between 2 pair of pins and then the total adds up to the other pair) as explained in your repair help forum. I also made sure each were not shorted to ground. The defrost element and it's thermostat check good. The evap coils are not forming any ice. My thermistor checks fine within range as you explain in a previous inquire from others. I conducted the test with a definite temp of 32 degrees F. Is there a reading for it at room temperature approx 70 F? I suspect the control panel on door since there is no defrost timer to check. Thanks Warren

What should the resistance ohms reading for a thermistor at ambient room temperature approx 65 to 70 degrees F. ? My thermistor checks fine within range when frozen in shallow cup of water. You state earlier here the range for 32 degrees and it was perfect. But you state a minimum also....is that minimum when not at 32 degrees?
