I just got my R1V2 220V. Got everything set up just fine, and started preheating to 230.
As soon as it reached 230, it started dropping. I waited to see if it would stabilize, but it kept decreasing. I shut off the roaster and started again. Now it won’t heat at all.
Update: This issue is sporadic. If it happens, restarted the roaster a few times gets it to work again. It seems like sometimes reducing the power to 0 makes it so the heater won’t turn on again until a reboot.
