I need access to the tech manual for the model listed in the title. I want to run a diagnostic but can't get it into diagnostic mode. I have tried selecting a button and pressing 25 seconds on, then off 2-5 seconds then on, then off, then on again. Even tried it adding once more cycle of on and off. Has the unit powered off when I started it and with the 1st press of the button the unit powers on and doesn't go into service mode. Tried 10 times using different lengths of time on and off because I know it tens to be touch. I also tried the selector knob ccw rotation 4-5 times, then one click CW, one click Cw, one click cw, one click CCW, then one click CW and nothing. I replaced the thermal fuse that had blown, and ran the unti and go noheat. Thought outbound thermistor was bad so replaced it with what I thought was correct model and I am still getting no heat and when I shut it off I get and F03 E01 error. I thought it needed to be reset after replacing them but can't figure out the sequence to clear the codes and try it. thanks to all who can help m out. JC
