Part 1: A Deep Dive into Error #30 Fan_ Limp.

. Introduction:

Navigating through the intricacies of Brivis Error Codes #30, (relating to Error faults #65, and #60) is pivotal for ensuring seamless Brivis Heating and Cooling Services.

This guide focuses on Brivis Motor Speed Sensor (aka TACHO) and the intricacies of Error #30, providing insights into effective troubleshooting and repairs.

Decoding Brivis Faults & Motor Error Codes:

Errors 30 and 65 often point towards anomalies in the speed sensor functionality. The Brivis speed sensor, identified by Part number: B014478, is integral to the motor control and driving electronic circuit, and is sometimes identified as the primary source of these errors, underscoring the need for expert Brivis evaporative coolers service.

Error 65, while related to the speed sensor, signifies that the motor or its circuit is locked out, often due to overheating. This error leans towards issues originating from the electronic circuit control module and is occasionally a precursor to Error 60 in Brivis models, highlighting the importance of a comprehensive maintenance on the cooling system.

At Fix2QIK we have designed the Brivis Part Checker to aid our technicians carrying out Brivis Repairs and Evaporative Cooling express maintenances, making us the best contractor of Heating and Cooling services in Melbourne since 2001.

This content Shows more of the Brivis Part Checker doing real job, field works scenarios near Melbourne. Take a look at the imbedded videos for an insight’s to better understanding how the Brivis Service and part’s diagnostic are done by professionals.

Conversely, Error 60 is indicative of concerns with the motor and its electronic driver circuit, unrelated to the speed sensor.

This article delves into the methodologies for testing the Brivis speed sensor, pivotal for diagnosing Error #30 Fan Limp.

Acknowledging the causes are many, emphasising the need for professional intervention.

Reason Causing Error #30:

  1. Speed Sensor: Sends precise speed information to the main control box.
  2. Control Module & Electronic Control Circuits: Faults in these circuits can trigger the error.
  3. Power Supply Variation: Erratic behavior.
  4. Fan Motor Obstruction: Mechanical troubles.
  5. Loose connection: Leads to misreading.

Conventional Methods | vs | Enhanced-Brivis-Parts-Checker.

The sensor, strategically positioned in the motor’s end plate hub, operates on an optocoupler principle, transmitting precise speed data to the control box.

Accurate identification of the defective sensor is crucial before exploring other components within the motor driving and control circuits.

It is noteworthy that obstructions in the optocoupler’s light path are extremely rare, reinforcing the sensor’s robust design.

At Fix2QIK, we employ a bespoke Brivis Checker, tailored for testing components in Brivis evaporative coolers and gas heaters, especially the contour models. This tool facilitates precise Brivis evaporative cooling service and repairs.

Practical Testing Methods:

1 | Conventional: Multimeters.

Traditional testing methods using DMM and VOM taking Ohm or Diode measurements on the three wires [ Green – Red – Blue ] while holding the white socket in place.

This method is perplexing and prone on misdiagnosis, especially when the technician has to work on the rooftop or in confined spaces.

For those without the Brivis – Parts – Checker, diagnosing Error #30 or #65 often a guessing game, even the factory technicians. It’s highly advisable to opting for a new sensor replacement every time, to circumvent misdiagnoses.

Disclaimer:

This article aims to impart knowledge and does not serve as a repair guide.

Overheated motors, circuit board issues, and overloaded power supplies can lead to hazardous situations. Attempting to repair the speed sensor without industry expertise is strongly discouraged by Fix2QIK.

While a combination of digital wall controller keys: FN + 1 and 4 (reset) may temporarily alleviate the errors, it is imperative to seek professional Heating and Cooling Service to address the root cause.

Electrical DIY endeavors can lead to perilous outcomes, emphasising the need for professional intervention.
