What people are saying

Rated 5 out of 5 by from So many features, what a difference. I bought this washer to replace my 2003 front load Frigidaire that still ran but was on its way out. Had plenty of time to research before making a choice. Have had it about a month and am very happy with it. What a difference in how my clothes look and love all the options for proper wash cycles.

Rated 5 out of 5 by from Gem of a Washer I bought this LG washer as a replacement to another make of washer which had given me nothing but trouble since the day I got it. This LG washer has been delightful and has had no problems. It does an excellent job of cleaning everything and has made washing day fun again. It also is very quiet when in the washing cycle.

Rated 5 out of 5 by from I really like it I had a whirlpool washer and did not have it for 2 years and it was bad. The LG is so much better and easy to do. I am so glad I went with it.

does this model have an internal heat sensor

Asked by: sizzle2009
Hi sizzle2009. We would need some clarification about what heat sensor you are inquiring about. Like all other washing machines, the ENERGY STAR® Qualified LG 4.5 cu.ft. Smart wi-fi Enabled Front Load Washer with TurboWash™ 360 Technology, Model # WM3900HBA has a thermistor which is essentially a resistor that changes its electrical resistance at varying temperatures. Thermistors are used in washing machines because their electrical resistance at various temperatures is known, it's easy for the washing machine to monitor a thermistor and detect when certain temperatures are reached. Thermistors are sometimes called NTC sensors or NTC Thermostats. Hopefully, that is the sensor that you are inquiring about? ^IV
