Yahoo! Operational kiln!!
This was a absolutely nerve wracking repair. There were not the same number of plugs on the new board as on the old and I plugged everything in off-by-one. Plugged in the kiln and heard power and smelled and saw a wisp of SMOKE! I ran for the circuit breaker and turned it all off.
Then I painstakingly re-did all the plugs again (ok goddess hop in here!). I plugged it back in and turned on the breaker. It said WAIT and then started flashing IDLE and the temperature. YAY!!!!!!!!!!!!!!
