πŸ”§ Repair of an Old Boiler at a Church in Sunnyvale – Successful Equipment Restoration

Recently, a church in Sunnyvale reached out to us for help repairing an old πŸ”₯ TELEDYNE LAARS PH 1200 IN 09 K 1A CW boiler that had stopped working. The client described the issue simply but seriously: ❌ "Boiler doesn’t work."

After arriving at the site and conducting a thorough diagnosis, we discovered that we were already the πŸ”Ž fourth company contacted for this issue. The previous three companies refused to perform diagnostics because the equipment was too old. However, our extensive experience working with various heating systems, including πŸ› οΈ TELEDYNE LAARS boilers, allowed us to quickly identify the problem.

βœ… Diagnosis and Solution

The cause of the malfunction turned out to be a ⚑ faulty flow sensor, which had failed. This is a common issue in older boilers, but with the right approach, it can be resolved without replacing the entire system.

πŸ”„ Repair Process:

  • 1️⃣ Diagnosis: Identified the issue – a failed flow sensor.
  • 2️⃣ Ordering the Part: We promptly ordered the original replacement sensor.
  • 3️⃣ Installation and Testing: Once the part arrived, we returned to the site, installed the new flow sensor, and conducted testing.

πŸ’° Total repair cost: Under $1,000, allowing the client to save significantly compared to the alternative of replacing the entire boiler.

🎯 The Result:

After the repair, the πŸ”₯ TELEDYNE LAARS PH 1200 IN 09 K 1A CW boiler was restored to full working condition, ensuring a reliable hot water supply. The client was satisfied, as the problem was resolved quickly, efficiently, and without the need for a costly system replacement.
