Electrical Device/Component

Summary The device described has experienced a failure (open, short, ground, etc.) The technician has verified this diagnosis as completely as possible without being able to operate system. There may be other devices that have experienced secondary damage that will not be evident until the listed part has been replaced. The technician has made every effort to provide a complete diagnosis, but will not be able to verify until the part has been replaced. At times the technician will recommend replacing additional related parts as a precaution or as standard procedure per the mfg.

Task The technician will remove the device/component and install the new part in the same location. Part to be installed securely. The integrity of all wire connections will be confirmed and repairs to connections made as needed, up to and including new connectors on wires. Once the device has been installed an operational test will be completed. If further diagnostic is needed, the diagnostic will be done as part of the original diagnostic. Any additional repairs will be approved before completing. With advancements in electronics, some functions may vary or no longer function. Other considerations with this type of repair Electrical Service Upgrade Wire size upgrade Fuse replacement Breaker replacement Installation of Micro Breaker System monitoring Electrical component Ohm’s testing Surge protection (Unit or Whole house)

PLEASE NOTE: The diagnosis was provided with the system inoperable, there may be secondary damage that is not evident until the new part/device is replaced once the part is installed the technician will have to "set up" and "program" the new device/part as well as operate the system in all modes to ensure proper functioning of the part and to confirm that there was no secondary damage apart at the time of the service appointment

PLEASE NOTE: Due to the severity of damage that was caused when the part failed, we are recommending the installation of a surge protector to guard against similar failures in the future. In the event of future failures we will not provide a part or labor warranty if the surge protector was not installed with the repair.

The technician will remove the device/component and install the new part in the same location. Part to be installed securely. The integrity of all wire and piping connections will be confirmed and repairs to connections made as needed, up to and including new connectors on wires. Once the device has been installed an operational test will be completed. If further diagnostic is needed, the diagnostic will be done as part of the original diagnostic. Any additional repairs will be approved before completing. There is no warranty on this part as it was supplied by client.

Diagnosis determined that the zoning panel is not functional and has an internal "short". Upon approval and replacement of the control board the technician will complete an assessment of the entire system while testing that the system is working with the new part. Recommendations for system will be made such as: enhancements, maintenance, upgrades, and energy efficiency.

Turn off the power to the receptacle from the main fuse or circuit panel. Unscrew and remove the cover plate; then use a voltage tester to make sure that the circuit is dead. Unscrew the receptacle from the electrical box and pull it out with the wires still attached. Note where the white and black wires are attached to the old receptacle. Attach the wires to the terminals of the new receptacle. If the wiring has a green ground wire, attach it to the green terminal on the receptacle or to the electrical box. Push the new receptacle back into the

electrical box and screw it in place. Screw on the cover plate and then turn on the power. Test for proper voltage and operation.

Replace existing GFCI (ground fault current interrupter). A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second. Due to the sensitivity of this device, "false" trips can occur when the device is getting "weak". Replacement is recommended when a clear reason for fault is not evident. If the fault continues after replacement it is typically an indication that a device connected to the circuit is beginning to fail. The technician can only detect a fault if it exists at the time of failure, some faults can be intermittent.

Secure the power to the circuit from the main fuse or circuit panel. Unscrew and remove the cover plate; then use a voltage tester to make sure that the circuit is dead. Unscrew the receptacle from the electrical box and pull it out with the wires still attached. Note where the white and black wires are attached to the old receptacle. Attach the new wires to the terminals of the receptacle. If the wiring has a green ground wire, attach it to the green terminal on the receptacle or to the electrical box. Push the new receptacle back into the electrical box and screw it in place. Route new wire to panel from outlet box location, new wire to be MC type #10 or greater with ground. Provide all required connections in main panel to new Breaker. Screw on the cover plate and then turn on the power. Test for proper voltage and operation.
