What I mean is, what do the steady-state DC voltages look like, and are they correct or incorrect for your circuit?? I was not referring to the INITIAL voltages at the start of the transient simulation. When the simulation is near 60 seconds and reached steady-state, do the bias voltages look right, or wrong?
Ok, by "bias voltages" you mean actually the
mean value of the voltages
averaged for instance over a time period of the source signal (e.g. averaged over a 1ms interval for a 1Khz source signal). Near 60 seconds from the beginning of .TRAN 60 UIC analysis, the heater's voltage and current looks good.

I meant the voltages in your circuit, at some or any or all circuit nodes. ?Were the FET's gate and source DC (bias) voltages about right, when near 60 seconds? ?Or were they wrong?
Ok yes, for instance the MOSFET's gate and source mean (DC bias) voltages (and current) near 60 seconds look good.
