A transfer switch failure might leave you in the dark. Modern Reliance Controls transfers switches are built with delicate electronics that can be damaged, resulting in the button failing. When your Reliance transfer switch does not operate as expected, apply the correct solution to repair it.
Transfer Switch Troubleshooting Guide for Reliance Controls
The transfer switch allows the outboard generator to run as long as there is no electricity supply. This device saves you time by conserving generator power and reducing manual labor. Learn how to repair your Reliance Controls for the transfer switch if it isn’t working correctly.
Breakers Tripped in the Trip CircuitElectrical surges can cause the transfer switch to trip, which will prevent it from operating. It’s the most typical issue and one of the first things you should look for when troubleshooting a transfer switch. You may call an electrician if you cannot do it yourself.

Voltage Transient with reliance controls
On the other hand, the transition voltage affects sensitive components in an automatic changeover switch. The voltage may harm the control boards during entry into the circuit board, causing them to malfunction.
The TVSP (transient voltage surge protector) is the best method to keep a transfer switch safe from transient voltage risks or malfunctions. You may use the manual to troubleshoot transients.

Damaged Wires
Reliance Controls for automatic transfer switches operate with a standard two-wire start system. When the electricity in your workplace is cut, a relay kept open by utility power closes, allowing these two wires to come together and cause the generator to start.
They will not make this connection if you disconnect them or the wires are facing damage.
-
Bad Controller
When there is an electricity shortage, a controller generally sends the proper signal to the generator. However, your lousy controller can’t send the correct alerts to your generator if you don’t have power.
If your controller isn’t working correctly, determine the source of the problem and repair or reprogram it. If repairing or reprogramming fails to solve the problem, you must replace the controller.
-
Damaged Solenoids
Solenoids may run too quickly, causing heat to build upon them. This heat causes burnout and failure. Also, loss due to neglect or buildup of dirt and grime within the generator occurs.
-
Utility Has Not Been Transferred
If your transfer switch fails to connect to the utility, it’s possible that the service disconnect breaker is open or the voltage is too high. As a result, you must verify whether the service disconnect breaker is available. If it is reopen, you must restart the service disconnect breaker or wait for the voltage levels to improve.

Generator Continues to Operate After Reliance Controls Transfer Back to Utility Power
This might happen in the engine cool-down period. It’s preferable to keep running the generator after the load reconnects to utility power so the engine temperatures can return to normal levels.
The engine shutdown period is usually on a set schedule to last 10 to 30 minutes, at which point the generator will be shut down and ready for another utility outage.

When the main power switch is turn on, the shore contactor does not activate after three to four seconds.
It is necessary to check the wiring, especially from the pedestal to the reliance controls transfer switch’s input terminals.
If the switch’s terminals are in the wrong connection, it has a protective mechanism that prevents it from engaging the contactor in a reversed polarity scenario. After that, please turn off the circuit, remove the device from its shore pedestal, and correct any input connections.
