Help with Doyon PIZ3G Oven
hey guys
oven has ignition, rectifies flame , cuts out after 33 seconds .
fan is not spinning mounted inside oven, check wiring diagram and saw no run/ start cap.
going to site to check overload relays , I am guessing the high limit is tripping . inner fan not running at all
any and all help much appreciated!
thanks , Ryan

Hey guys just wanted to give you a update.
Post visit and tech support we diagnosed that the VFD was not putting out power on the LOAD terminals of the VFD to power the 3 phase motor.
i also discovered that the pressure switch had been internally bypass by someone taking the NC and NO wires and putting them both to the NC terminal on the pressure switch. no wire on the NO terminal and the NC to the NC terminal .
this allowed the oven to fire up and rectify before tripping a limit without the fan running.
new pressure switch and vfd needed .
will update .
shoutout to the Dayon techs , those guys are friggin amazing !!
