Very Disappointing

[Jimmo]

I again put chicken thighs on my 6 week old pro 1300 purchased from Lowe's. The 3rd day I had the grill I cooked thighs on 350 the thighs took 65 minutes to reach 170 degrees. Since then the grill started to take longer each time. The grill says it is at the temperature that I set it at, but the independent oven thermometers say it between 100 to 150 degrees lower. Today I but grill on 400 degrees. When the grill said it reached 400 I touched the sensor bar with my thermopen it said 265 degrees. The oven thermometers read 280. The chicken at 2 hours was 140 and bloody. Lowes is sending me new grill I HOPE it works! OR IM DONE WITH PITBOSS
