Fast, Certified Pool Heater Repair in Vaughan

 These are common error codes for the Hayward Universal H-Series (FDN/ED2). An IF (Ignition Failure) means the unit failed to light after several attempts, often due to a faulty igniter or gas valve. An LO (Limit Open) code indicates a safety limit—like a high-limit or pressure switch—has opened, cutting the circuit to prevent overheating. We carry these specific Hayward sensors and igniters on our trucks to get your Vaughan pool warm again in one visit. 

A roll-out switch is a one-time safety device that cannot be reset. It trips when flames are detected outside the combustion chamber, usually due to a blocked heat exchanger or soot buildup. You should never bypass a roll-out switch, as it is your primary protection against a fire hazard. A TSSA-certified gas technician must diagnose the cause, clear the obstruction, and replace the switch with a factory-authorized part. 

We offer Same-Day or Next-Day service for Hayward, Jandy, and Raypak heaters. If you live in Maple, Woodbridge, or Kleinburg, call (647) 498-5633 before noon to speak directly with a gas tech. You skip the call centre and get an immediate arrival estimate.

No. In Ontario, gas appliance repairs must be performed by a TSSA-certified technician. DIY repairs on gas lines or safety circuits can void your warranty and lead to dangerous gas leaks or carbon monoxide issues.
