COMPONENT TEST
NOTE:
1. The most common cause for control failure is corrosion on connectors.
Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures
2. If this is a new product check all connections before replacing parts.
1. All test and checks should be made using a VOM or DVM having a range of at least 20,00 ohms or greater.
2. Be sure to check all connections before replacing components. Look for broken or loose wire, failed
terminals or wires not fully seated into the connectors.
3. Resistance checks must be made with power disabled form oven, and with wiring harness or connectors
disconnected.
Before testing any components, perform the following checks:
WARNING
• Disconnect power supply before servicing
• Replace all panels and parts before operating
• Reconnect all grounding devices after servicing
- Failure to do so can result in death or electrical shock
NOTE: Below Ω value were tested at room temperature (77F/25°C)
Convection Motor 1. Refer to page 3-8 for Disassembly
2. Measure the resistance
