Are they good, bad, sometimes good and sometimes bad? LG appliance parts are hard to come by, frequently with a two week waiting period. I just bought a Supco high limit switch for a LG dryer and the switch tripped once and never reset. I since found out the it tripped because the flapper in the vent cap was not opening freely. I modified a Whirlpool high limit switch (mounting bracket was different) and it is working well.
