Title: Samsung Dryer Shuts Down in Sensor Dry
Post by: Blaiser on May 28, 2014, 09:31:49 PM
I have a Samsung DV330AGB Gas Dryer that shuts down within 3 1/2 minutes with a full load of wet clothing. It will start up again if I hit start. The Dryer works completely fine in Time Dry. But the minute I put it on any Sensor Dry Setting it shuts down prematurely at the 3:47 minute mark. I opened up the Dryer and check the Sensor Connections and they were connected. I even removed the plugs from the Sensor Bar itself to check to see if there were any loose connections. Any suggestions would be greatly appreciated.

It does not sense the wet clothes. I wouldgo strait to the main pcb and verify the circuit, if ok replacr main pcb.

I have a new PCB Board coming tomorrow, (June 2nd) will install and let you know. I already replaced the Thermistor with NEW and no good. Waiting for new board. I'll keep you informed.

Thermister has nothing to do with sensor dry, just operating temp. THE bars, wires and pcb do. LMK.

Just replaced the OLD PCB with a NEW PCB same problem. Starts off with 58 minutes then within 3 1/2 minutes its down to 5 minutes and then shuts down with a full load of damp towels.
Should I be thinking sensor bars ?

Verify the sensor circuit.

UPDATE !!!! Problem Fixed !!!!


Since I all ready replaced the Thermistor, and Main PCB Board I thought I'd spend $2.36 cents for a new Sensor Bar. I order the (2) new sensor bars and they came in today. First off the Sensor Bars were not a direct replacement, they did not fit into the Sensor Bar Base - they were not shaped correctly and they sat about 1/4" taller in base (returning them) but after removing the original bars there was a large amount of Lint Build up under the sensors. So I removed both sensor bars and cleaned them with a High Pressure Air Compressor. Plugged the old bars back in and BINGO that fixed the problem. NO MORE SHORT CYCLING. I ran a test load of freshly washed shop towels and placed the Dryer in Sensor Dry on Heavy Duty and it ran perfectly!


Also be careful when replacing the PCB Board there is a Diagnostic Port that can be mistakenly used that the Thermistor harness fits perfectly in and that will give you a "TO" Error (Thermistor) if you plug the wrong harness connector in the Diagnostic Port. The Main PCB Board will not detect the Thermistor and throw a "TO Error Code"). Some times you learn by doing something STUPID but I'm glad STUPID Found the problem!! O0
