When light from the burner flame strikes the photocell, its electrical resistance changes, signaling the burner control unit that ignition has occurred. If no flame is detected, the control unit shuts down the burner as a safety measure.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this QRB1 photocell compatible with my waste oil burner?\u003c\/h4\u003e\n\u003cp\u003eA: This QRB1 photoresistor is designed to be compatible with standard QRB1 flame detector sockets found on many oil burners and waste oil heaters. We recommend verifying your burner's flame detector socket type and specifications before purchasing to ensure a proper fit.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I install the QRB1 flame detector?\u003c\/h4\u003e\n\u003cp\u003eA: Installation typically involves removing the old or faulty photocell from the burner's detector socket and inserting the new QRB1 unit in its place. Always ensure the burner system is fully powered off before performing any maintenance. If you are unsure, consult a qualified heating technician.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a QRB1 photocell and what does it do in a burner system?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A QRB1 photocell is a photosensitive (light-sensitive) resistor used in oil burner and boiler systems to detect whether a flame is present.
