Several weeks ago, I put in an email help ticket to HR for mid batch heater failure. You could see the logs indicate it calling for heater and it heating and then cooling off. Didn’t get a response. Called, they had me do the heater tray reset and try again. Still failed. Called, paid the $45 fee and got a tech on a call a couple days later. Sent special software that uses the “drain” relay for the heater and moved the wires for the heater to the other relay. Going to try again. Fingers crossed. Probably need a new relay board, though they used Omron G5RV relays which are readily available and I have the repair tools.
The EE in me says it could also be the signal from the main board, but have no way to diagnose without more detailed machine information.
Oh, and my support ticket numbers are in the 161 and 171
thousand range. That’s a lot of tickets.
