After dealing with a situation where the original component had worn out over time, we installed this replacement part. Everything powered back on correctly afterward. Would probably order again if needed.

After dealing with a situation where the appliance suddenly stopped working properly, we installed this replacement part. Cooling performance seems stable again. Worth verifying model number before ordering though.
