Jenn Air range help

One of the right hand side elements stays on high. Replaced cook top switch, however I mistakenly reversed the bottom two wires on switch, turned power on and kicked out breaker. Figured I damaged the new switch so I put in another switch and wired correctly. Reset fuse at bottom of oven turned power back on and both right side elements stay on with switches shut off. Is it a thermostat problem or what?
