Unit will go into Sabbath mode with target temperature of 100 deg F. Check that cooling Fan is ON.
Section 4 – Troubleshooting Charts Section 4 – Troubleshooting Charts Voltage and Continuity Symptoms All the voltage test points will be at the relay board. No clock display While power is on check the following Voltages: 1) P3 pin 4 - P3 pin 5 = 5 VDC (check both relay and display board). 2) P3 pin 6 - P3 pin 7 = 12 VDC (check both relay and display board) If one the above voltages not present check connection to P3 connector. If cable is properly connected, then replace it.
Dacor Renaissance Wall Oven Service Guide Symptoms No elements cycling in ALL modes (cont.) Bake element only is not cycling during preheat, bake, conv bake, conv roast, self clean, HOLD Page 8 All the voltage test points will be at the relay board. 10) L1B - L2 = 240 VAC (Lower elements).
Section 4 – Troubleshooting Charts Symptoms Bake element only is not cycling during preheat, bake, conv bake, conv roast, self clean, HOLD (cont.) Broil element only is not cycling during Preheat, Bake, Conv Bake, Conv Roast, Broil, Conv Broil, and Self Clean Convection element only is not cycling during preheat and Pure Convection All the voltage test points will be at the relay board.
Dacor Renaissance Wall Oven Service Guide Symptoms Convection element only is not cycling during preheat and Pure Convection (cont.) Convection Fan does not run during Preheat, Conv Bake, Conv Broil, Conv Roast. Page 10 All the voltage test points will be at the relay board. 5) If above mentioned terminals do not read 240 VAC when suggested mode is running and the oven started cold then the convectionl relay is not cycling or is damaged. Replace the relay board. Upon replacement do the same test again.
Section 4 – Troubleshooting Charts Symptoms Convection Fan does not run during Preheat, Conv Bake, Conv Broil, Conv Roast (cont.) Cooling fan does not turn on at designated turn ON temperature Latch motor not running during Self Clean All the voltage test points will be at the relay board. 12) If connection is good, disconnect convection fan and measure the resistance directly. Resistance should be approximately 13 ohms across the terminals.
Dacor Renaissance Wall Oven Service Guide Symptoms Latch motor not running during Self Clean (cont.) No oven light only No heat in any cooking mode Oven sensor failure Failure Code U30/31 Latch switch circuit Page 12 All the voltage test points will be at the relay board. 7) If there is continuity, check resistance on these test points: 8) Check upper/single latch motor, Neutral - P11 Pin 1 = approximately 18 ohms. 9) Check lower latch motor, Neutral - P11 Pin 9 = approximately 18 ohms.
Section 4 – Troubleshooting Charts Membrane Continuity Test To test for non-functioning membrane touchpad, disconnect the membrane/touchpad ribbon connector from the ERC controller. The ribbon connector is numbered from 1 to 14 counting from the top down. Use an Ohm meter to test across the following test points. A reading above 5 Ohms across any of the test points listed below indicates the membrane is bad and needs to be replaced.
