I received a new ET-733 for Christmas and have gotten to use it several times so far. One of the probes reads right on, the other probe is reading about 100 degrees high. I have tried changing the batteries, changing the bad probe into the other port hole and it still reads very high. By doing this I am fairly confident it is a problem with the meat probe and not a problem with the transmitter/receiver. There does not appear to be any breaks or tears in the probe wire. The wire seems to be pushed in the probe correctly. Anyone ever had this problem before or know how to fix it? Thanks in advance.
