Question about KitchenAid Ovens
The character befor the last 8 in model is a letter. The model is probably YKERC607HS8.
Since the oven is clicking, then relays are likely working. The relays must be tested reading voltages, or replacing them. Testing on relays can be done at last. The technician can test initially if there is volts at temperature probe and element, that is already an indication that relays worked. For safety reasons it is better if the user does not perform tests that must be done with power on (volts reading).
The appliance can be tested almost entirely using Ohm meter on parts after disconnecting power.
The first part that can be tested is the temperature probe. This is located inside the oven cavity, and it is indicated as part nr.22 in diagram 1 below. Here the part: sensor.
The probe can be tested removing it from cavity and reading Ohms at its terminals. If the probe is good it will read low impedance or zero at room temp. If the probe shows no continuity at room temperature (circuit open), then the part needs replacement.
Other way to test the probe is by jumping its contacts and starting the oven for a short time. If oven starts heating, then the probe was responsible for the problem. The oven can easily blow elements with probe sensor contacts jumped. Testing must be done by a competent person.
When the oven is not baking or broiling, the temperature sensor is often responsible.
If the probe is good, then the elements must be tested. When problem is caused by an element you usually do not loose bot baking and broiling functions at once. If oven is not baking and not broiling, then the elements are unlikely responsible.
Elements must be tested reading impedance. If one of them shows no continuity, then the part must be replaced.
Next step will be checking if there is continuity in wiring between elements and sensor, and between sensor and oven electronic control contacts.
After that the relays and the control board are tested reading voltages. The relay board is placed at the back of the oven on the left hand side watching appliance from front.
The problem causing the symptoms you described is usually the temperature sensor. Test and eventually replace it .
