I am new with this Maverick ET-733 Wireless Probe. However, I have used it 3 times now with success .... until yesterday that is. I don't remember what steps or procedure I set it for what I wanted the first 3 times I used it. I don't remember if I set it all up before inserting the probes in to meat or after I entered the probes into the meat. Yesterday, I smoked four 1 1/2# Hormel Pork Loins. I put the 4 pork loins on the 3rd shelf 6 roasting ears on the top shelf. I then ran the cables thru the top vent and inserted the 2 probes into a loin on the far right and one into a loin on the far left. I then shut the door and plugged the cables into the transmitter. I then turned the transmitter on and the receiver on. I set the receiver for BBQ (pork) on both probes and it automatically put 160* on the receiver. .... That is where the problem began as the receiver would never show the temp of the probes thru the entire smoking process, it would only show 3 blank lines for each probe, so I kept having to go out and check the temp on the transmitter. I tried resetting this thing more times than I can count with same results each time. I tried resetting the receiver right next to the Smoker and in the house and it didn't matter, it wouldn't show the probe temps. I also tried unplugging the cables and plugging them back in. After I was done smoking and cleaning every thing up and putting it away, I sat down in my chair with the cables hooked to the transmitter and transmitter on the coffee table and I sitting about 6-8 feet away and programmed the receiver again and it worked perfect showing the temp in the house at 76*. So, does everything have to be set up before inserting the probes into the meat in order for it to work right?
