What to do if the Dacor DMO2420 monitor fuse blows when plugged in?
If the monitor fuse blows when the power cord is plugged into the wall receptacle, check the monitor switch, relay (RY1) primary interlock relay (RY2), door sensing switch, and secondary interlock switch before replacing the monitor fuse. If the monitor fuse is replaced, the monitor switch must also be replaced using part FFS-BA016/KIT as an assembly.
