Smith 5UF8 PMF Control Relay is an OEM AO Smith replacement relay that actuates the compressor or pump circuit in AO Smith water heating and heat pump systems. Used by service technicians to connect the main control board to the compressor or pump, the PMF relay switches power to those loads during normal operation and safety cycles. In AO Smith literature, relays designated as compressor control relays appear in replacement kits and parts catalogs, including 9007476005 (Kit, Compressor Control Relay) and 100112042 (Compressor Control Relay), illustrating the relay's role across multiple AO Smith models. These relays are commonly referenced in HPWH and water heater service documentation as the control point for the compressor in AO Smith electric heat pump water heaters and related equipment. For exact electrical ratings, mounting specifications, and wiring details for the 5UF8 PMF Relay, consult the AO Smith replacement parts catalog or the service manual for your unit to verify compatibility before installation.\u003c\/p\u003e\u003c\/div\u003e","brand":"AO","offers":[{"title":"New","offer_id":51660024316206,"sku":null,"price":231.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4fcf7ecc-0dda-45f9-8757-a17906c0cd9e.jpg?v=1769531918","url":"https:\/\/plgautomation.com\/products\/a-o-smith-5uf8-pmf-control-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
