Oven only heats to 170 degrees in 22 minutes .
On preheat and bake, top element comes on for 5 seconds, bottom element comes on for 30 seconds,alternating, convection fan does not show on display, but I can hear the fan running.
When turning broil on, top red light shows on display but broiler does not come on.
Both elements read 110 volts and temperature sensor reads 1100 volts when tested with a current tester. I checked the control panel and could not see
anything unusual.
Any advice would be appreciated.
