Hi, When using Bake, the unit indicates it has come up to the required temperature but is luke warm inside and never gets any hotter. MGT THERMO Assembly, pn 1434? Thanks, Dale

Hello Dale, Thank you for the question. We suggest Testing the Sensor. To test the sensor with a multimeter, remove the sensor from the PCB. Measure the resistance terminal to terminal (Ohm mater scale: RX1000) Black to Red 6.2K ohms, Red to White 3.1K ohms and Black to White 3.1K ohms. We hope this helps!
