Check the thermostat. On some of the lovely models, they put multiple thermostats, in which 1 will arbitrarily pop-especially when you get the low temp errors.

I 'try' to remember to run my machines a few degrees below the factory setting. It gives me a bit of a buffer of sorts, and helps with not popping so many thermostats. It may or may not help you, but it's just something I do and it works well. It is case-by-case of course.

Thanks Cobiray. I'll check these items tomorrow and let you know how it pans out.

Point taken Schooltech. I will look into making the adjustment.

Thanks guys.

Have a good night.

Try a new fusing unit too. They are user replaceable on these things anyway. I think I've had to replace an IH unit before too, can't remember if it was 544 tho.
