Pool Heater Repair in Rancho Santa Fe, CA
A heater that clicks but never lights, fires and drops out, or refuses to start at all is usually failing somewhere in the ignition sequence. We trace it step by step before we quote.
Will Not Fire
When the Heater Clicks but Never Lights
A pool heater that calls for heat, clicks, and then goes quiet is one of the most frequent no-heat calls we get in Rancho Santa Fe. The blower spins up and the gas valve opens, but the flame never catches. The fault almost always lives in the ignition path, not the burner itself.
The Igniter
The igniter produces the spark or the glow that lights the gas. If it is cracked, worn, or coated, the heater tries and fails to light, then locks out. We test the igniter output before we move on to anything else.
The Flame Sensor
The flame sensor confirms that the gas actually caught. If it cannot read the flame, the gas valve closes as a safety step and the heater shuts down. A coated or failing sensor is one of the most common causes we find.
Flow and Pressure
Why Water Flow Can Shut the Heater Down
A pressure switch inside the heater confirms that water is moving through the heat exchanger before the unit is allowed to fire. If a dirty filter, a closed bypass valve, or a pump on low speed drops the flow below that threshold, the switch opens and the heater turns off to protect itself.
That means a heater that will not stay on is sometimes a filtration problem, not a heater problem at all. We check the pressure switch under load and look at the filter and bypass together, so we do not replace a part that was never broken.
The Process
How an Ignition Fault Gets Fixed
We follow the ignition sequence in order, confirm the failure point, and quote before any repair.
Trace the sequence
We watch the heater through its start cycle to see where it drops out, whether the igniter fires, whether the flame catches, and whether the pressure switch holds. That tells us which part is failing.
Confirm and quote
We confirm whether the fault is the igniter, the flame sensor, the pressure switch, or a flow issue from the filter or bypass, and give you a written quote before any repair work begins.
Repair and verify
We replace or clean the part that failed, run the heater through a full ignition cycle, and confirm it fires, holds the flame, and reaches your set temperature before we call it done.

FAQ
Ignition and No-Fire Questions
Questions Rancho Santa Fe homeowners ask us about a heater that will not fire or will not stay running.
A clicking sound with no ignition usually points to the flame sensor, the igniter, or the gas valve. The heater hears the call for heat and tries to light, but either the spark fails, the sensor does not confirm a flame, or gas never reaches the burner. We walk the ignition sequence in order to find where it breaks down before we recommend a part.
