Questions & Answers

For Ge Refrigerator Defrost Timer (Part Number: OEM6185133)

1 Answer

Yoyaya, Based on the information provided it sounds as if you did not get the evaporator and airflow components completely defrosted after replacing the timer and the air to the refrigerator side is blocked. defrost it down and make sure all the frost and ice are melted out, then try the operation again.

Greg for Model Number ZIS42NCA

Freezer is fine, but refrigerator door was left ajar overnight and would not cool the next day. Unplugged unit and left doors open for 24 hours, then everything worked fine. 1 week later went grocery shopping & after loading noticed foo was not getting cold in refrigerator, same result next morning. Freezer fine through all. Suspected maybe was defrost timer, turned it with screwdriver until "clicked" & compressor/fan turned off; immediately noticed water on sides of freezer & inside refrigerator, let defrost for a few hours, then turned the timer back until compressor kicked on. Things now seem to be cooling properly but I suspect the defrost timer is bad so ordered a new one, which will arrive in 2 days. What do I do in the meantime? Do I need to manually turn off timer every 6 hours & let defrost for 30 minutes, then turn back on?

1 Answer

Greg, Yes, turning the defrost on a few times per day and letting it stay on for 30 minutes would be the best option since it does sound like it is not going into defrost on its own.

John for Model Number PTC22SBMALBS

GE Profile drain freezes and the bottom of the freezer fills with Ice. I manually defrosted the unit, flushed with hot water which drained into the pan. blew the line out. wrapped a 12 gauge wire around the coil and into the drain. worked well for months. issue returned. attempted to replace the defrost timer. the original part was wr9x490 replacement part wr9x502. the fridge does not function with the replacement timer. put the original timer back in and the unit comes on. any thoughts? thanks

1 Answer

John, the new defrost timer may have been in the defrost cycle portion and can be rotated into run mode by using a flat head screwdriver. However, in regards to the defrost drain freezing up, it can certainly be from the original defrost timer short cycling or from a clog in the defrost drain. Commonly these clogs occur where the defrost drain tube goes to the drain pan, especially if there is a lot of dust or pet hair.

Michael, So to normally run without the defrost heater on pins 3 to 4 should read closed or continuity and pins 3 to 2 should read open or no continuity. Any other reading and you will need to replace the defrost timer.3 to 1 is your power to the timer so it runs.WR9X502

Jim, The original defrost timer had a 35 minute defrost cycle, the replacement defrost timer has a 25 minute defrost cycle. These are the "total" defrost cycle times. The defrost heater is controlled through the defrost heater and opens at 53 degrees regardless of time(usually takes 10 to 15 mins.). Once the thermostat opens and "turns the defrost heaters off " the remainder of the total defrost tome is used to evacuate the defrost water and condensation into the drain pan, then the compressor should start, run and start cooling.

Dave, Based on the wiring diagram, the defrost timer WR9X502 is a 6 hour accumulated run time("compressor time") defrost timer with a 25 minute defrost cycle time. The AP2061708 Defrost timer is correct, for the model number you supplied, and is in stock and available at this time. Thanks,

Jose, With having water dripping from the ceiling of the refrigerator and icicles forming in the freezer compartment then this will likely be a air leak around the door gaskets and will want to check the bottom of the refrigerator door gasket and the rest of the gaskets for good and proper seal.

Hello Wyn. If both heater are good, you have a sealed system failure and will need an HVAC tech to come and repair the unit.
