if the TAZ we has now has the 2.0 schnozzle then it might use the 4.7 ohm
resistor as seen here:

of course the printer will work with a different resistor as long as it
provides enough heat to print. Worst case we have to insert M220 S50 to
slow it down to half speed printing until we get a better resistor...
what value resistors do you have? any special glue?

this is what i pull up for the part - 6.8 ohm:

sounds like the most common reason for these failing is over temp from miscalibrated
thermistor - i did find those 3 i got for the type a machine and if it's the same part
i'll bring them in.
