Pool Heater Repair overview
Toronto's swimming season is short, so a pool heater that fails in June or September can take a real bite out of summer. BrightOak Appliance Repair services residential gas pool heaters and heat-pump pool heaters, helping homeowners get water temperatures back where they want them.
Pool heaters live outdoors through humid summers and freezing winters, which exposes them to corrosion, debris, rodents and water-chemistry effects. Our technicians look at the heater itself and the conditions around it, including water flow and pressure from the pump and filter system.
Common pool heater problems and symptoms
Heater won't ignite
Gas heaters may have igniter, flame sensor, gas valve or control faults. Low water flow can also prevent the heater from firing as a safety measure.
Heater turns on and off repeatedly
Short cycling can come from dirty filters, low flow, a faulty pressure switch, thermostat problems or overheating.
Water not reaching set temperature
Undersized equipment, scaled heat exchangers, airflow problems on heat pumps or cool nights can all limit heating.
Error codes on the display
Most modern heaters report faults by code. We interpret the code and test the related sensor or component.
Corrosion or leaks
Poor water chemistry can corrode heat exchangers and headers, leading to leaks and reduced efficiency.
Heat pump fan or compressor issues
Heat-pump pool heaters can have fan motor, capacitor, refrigerant or defrost faults.
How we diagnose and repair your pool heater
We verify water flow and pressure, check filter condition, test ignition and safety controls on gas heaters, inspect heat exchangers for scale or corrosion, and on heat pumps check fan, compressor and refrigerant circuit operation.
Typical repairs include igniter replacement, flame sensor and pressure switch replacement, thermostat and sensor replacement, control board repair and fan motor or capacitor replacement. Heat exchanger replacement is quoted separately.

Repair or replace?
Pool heaters often last 8 to 15 years depending on maintenance and water chemistry. Ignition and sensor repairs are usually economical.
A failed heat exchanger on an older gas heater may make replacement more sensible. We give you a clear comparison.

Pool Heater Repair FAQs
Low water flow from a dirty filter or a pump issue is a common cause. If flow is good, the igniter, pressure switch or control may need testing.
