My replacement heater assembly works great. With my old assembly, the roaster suddenly stopped working, with the temp never getting above room level, leading to an E4 error. A multimeter test against the heater leads showed infinite resistance, which likely means the coiled resistive wire in the assembly broke. Not a surprising outcome for a heat element after 10+ years.
A few tips:
(1) If you have an old Gene Cafe, with the old inlet temp sensor (white leads instead of blue), please note that the resistance across the old inlet sensor's leads is in the megaohms at room temp (mine is about 4.5 megaohms). The troubleshooting guide lists a much lower resistance, but that's for the new inlet sensor.
(2) While replacing the heater assembly, considering removing the fan entirely and thoroughly cleaning the screen below it.
(3) There are two metal rollers that fall out easily while doing this repair. They go back easily enough, too, but if you find them and are wondering what they are, now you have a clue.
(4) To ensure that the two roast chamber guides are rotated properly in sync, it helps to have the roast chamber installed before you screw down the new heater assembly. This is a bit of a fidgety trick, and you'll need to remove the roast chamber once everything is tightened to be able to put the cover back on. But this seems preferable to realizing afterward that the guides are not lined up.
