Leroy B Colorado Springs , CO January 19, 2015 Appliance: LG Refrigerator LMX25981ST Lg Refrigerator Lmx25981st / Ast4lga: Two issues water in the bottom of fridge and clicking noise. How to replace Water Filter Head. The old filter head was broken at the supply line side connector fell out. The clicking noise eventually caused the fridge to warm up and stop cooling. The clicking was the overload relay tripping. The Start solenoid on the compressor was an Embarco TSD part 513604044. APP does not have that part nor does any else found a similar one on ebay but I ordered the PTC assembly 6749C-0014E. I removed the overload relay and capacitor from the TSD used two pieces of wire and connectors to create the circuit using the PTC. As soon as I plugged it in the compressor started working and cooling the fridge. problem solved. Thanks APP for the parts I should be good to go another 7 years. 22 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
