Arrived at location on 10/31/22 - Went to turn on and it would not light. Had good spark. Noticed code on temp control was saying bad temp probe. Tested resistance and found it was good according to manufacturers chart. Found temp control to be bad. Meet up with Dan to get a used one off his truck. Unit is up and running for now but customer would still like new one ordered. Will order part and return. Returned to location on 11/3/22 - Shut power off to right side unit and removed control box assembly. Installed new control box assembly and powered unit on. Turned unit on it it fired right up. Set to 350 and verified unit cycled.
