Let’s face it, these kilns are heavy!. The last thing you want to do is to start wrestling around with them to get at a component that needs to be replaced. All Scarab kilns are designed with a Removable Chasis which holds all the main electrical and electronic components. Just remove the screws that hold it in place and slide it out. You can even disconnect the power cord and ship the whole thing back to Skutt for testing if necessary.
One of the most problematic components of kilns has traditionally been the relays. Mechanical relays have a limited life which is why Skutt has upgraded all Scarab Kilns with Solid State Relays. These relays or kept cool with a fan mounted in the side of the kiln (not necessary on the Mini Scarab because the Amps are so low).
