Final answer:
If a technician wires around a limit switch and the fan becomes defective and does not run, several issues can arise, such as continuous running without control, potential hazards, and poor system performance.
Step-by-step explanation:
If a technician wires around a limit switch and the fan becomes defective and does not run, several things could happen:
- The fan may continue to run continuously without any control from the limit switch. This can potentially cause overheating and damage to the fan motor.
- In case of a malfunction or failure in the fan, without the limit switch to detect and stop any hazardous conditions, the fan may continue to operate even if there is a problem, such as a blocked air vent or a worn-out motor bearing. This can lead to further damage or even a fire hazard.
- If the fan fails completely, it may result in poor air circulation and inadequate ventilation in the system. This can impact the overall efficiency and performance of the system.
