Furnace Repair ICP T8MPL075B12B1 — San Mateo

Sharon from San Mateo noticed that her furnace was working inconsistently: the fan kept turning on and off randomly, and the system would not start properly. She contacted us to check the unit located in her attic.

✅ What our specialists did:

We performed a full diagnostic and identified the cause — a failed control board. This part is essentially the “brain” of the furnace: it manages all processes. Once it fails, the system starts behaving unpredictably.

✅ Solution:

To restore the furnace, the control board must be replaced. The total cost of repair is over $1000. Diagnostic is free when the repair is completed.

How common is a control board failure?

This is one of the most frequent issues with furnaces. Causes may include:

• power surges,
• overheating,
• moisture (especially in attic installations),
• natural wear over time.

When it makes sense to replace the board:

• ✅ If the furnace is relatively new (under 10–12 years).
• ✅ If the rest of the equipment is in good condition.
• ✅ When the repair cost is significantly lower than purchasing a new unit.

When it’s better to replace the entire furnace:

• ✅ If the furnace is over 15 years old.
• ✅ If there are other major issues (corrosion, cracked heat exchanger, frequent breakdowns).
• ✅ When the repair cost reaches 30–40% of the price of a new furnace.

❓ What does it mean if the fan keeps turning on and off?
It’s usually caused by a faulty control board, and professional diagnostics are required.

❓ How long does the repair take?
In most cases, replacing the control board is completed within one working day.

❓ Why does the repair cost over $1000?
The control board is a complex and expensive part. We only use original certified components, ensuring long-lasting reliability.
