Ge WR51X10038 Refrigerator Defrost Heater OEM Part

Replaced defrost heater, temperature and defrost limiter thermostat. After taking the cover off the air chiller I found the coils frozen solid and defrosted it with a hair dryer. Once defrosted I remover the heater coil to test it it was fine, then I could see the defrost limiter was broken and as I put the unit back together I broke the heater tube (it is glass) so I ordered all the parts that might be defective and replaced them for less than the charge of having some one come to check it out.

Replaced defrost limiter thermostats and glass heater.

Replaced defrost heater and defrost thermostat.

First I replaced the defrost timer because I read this was a likely culprit. I didn't have a multimeter to test. After a week the problem re-surfaced. I researched further and found that if the Defrost Limiter Thermostat was exploded that it was probably bad. By exploded I mean that the seals on either end were uneven and burst. I replaced the thermostat and it looks like the problem is solved!

Watched videos on this site , ordered parts and installed as directed (easy work). My refrigerator is working fine again.
