    Smoker is set at full on readout says 270.
    Altitude Minnesota. Outside temperature 80 degrees.

    Oh look, being photo bombed by a Stoli BlackBerry Fresca...I'll take of him now.

    Do you have a pic of your smoker?

    Where do you have the Maverick food (straight) probe?

    I don't Bear but it's the #####0910 model rear digital readout top vent.
    Probe is in the center of the unit.

    So you're saying it's set at 275*, the readout says 270*, and your Maverick is reading 235* with the smoker probe in the center of the unit.

    I would first check my Maverick by boiling a pot of water, and holding the end half of the Maverick smoker probe in the boiling water. It should read about 212*.

    If that reads OK, I would try heating your MES again, but this time put the probe close to the MES temp sensor (Looks like a toggle switch, and should be on the back wall, to the right of center). If they're still more than 10* different, I'd call Masterbuilt & tell them about it.

    Keep me posted.

    If it was the other way around, I might say just ignore what the MES says & go by your Maverick, but in this case if you're setting it at 275* (Maximum setting), and you're only getting 235*, that means 235* is your maximum actual smoker temp.

    I would definitely call them, because you paid for a smoker that goes to 275*.

    I've got the same MES you've got. Using my ET-733 for the first time today. I set the BBQ probe for a 235 temp with high 250 degrees and low 225. I've had the MES therm set anywhere from 215 to 230 because the MES temp has been swinging (according to the Mav) from 225 to 246 and back for 3 hours while I've been smoking 2 racks of ribs. I had the probe near the front of the 2nd rack but when I took the ribs out to wrap foil around them I moved the BBQ closer to the back wall, presumably closer to the MES temp sensor. The temp is still swinging between 232 and 239 but that's an improvement. The MES digital temp display is running 7-8 degrees lower.
