Albert L. for Model Number lmv1813st LG My lg microwave is still giving an error code of F-4 after I replaced the 6501w1a013a sensor. Only sensor cook is affected. What else could be causing the error code. I did check the resistance in my old sensor, R-B = 6.44K, R-W = 3.213k, W-B = 3.2k, W-B = 3.21k. Thank you.

Since it is the part interpreting the information sent to it, it could have an issue with the circuit that reads the information sent to it. Read More...
