This specialized Single-Pole Double-Throw (SPDT) relay serves as a \"fan delay\" or \"anti-short cycle\" timer, managing the crucial transition between the thermostat's call for cooling and the engagement of the indoor blower motor.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eTechnical Performance:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eOperating on a \u003cstrong\u003e24V control circuit\u003c\/strong\u003e, this relay is designed to keep the indoor blower running for a short period (typically 30–60 seconds) after the compressor shuts off. This \"off-delay\" allows the system to harvest the remaining cooling capacity from the evaporator coil, significantly increasing the SEER efficiency of your HVAC unit. Its \u003cstrong\u003eSPDT configuration\u003c\/strong\u003e ensures that it can manage both the primary fan signal and an auxiliary circuit simultaneously without electrical interference.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 1: Efficiency-Boosting Off-Delay:\u003c\/strong\u003e Maximizes energy savings by circulating the residual \"coolth\" from the coil into the living space after the cycle ends.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 2: Anti-Short Cycle Protection:\u003c\/strong\u003e Helps prevent rapid compressor cycling, which protects against premature motor burnout and excessive wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 3: SPDT Contact Logic:\u003c\/strong\u003e Versatile Single-Pole Double-Throw switching allows for complex control of fan speeds or accessory components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeature 4: Compact \"Snap-In\" Design:\u003c\/strong\u003e Features a standard mounting bracket and 1\/4\" male spade terminals for a fast, secure electrical connection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1370738 (Replaces B13707-38)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Goodman \/ Amana (Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Time Delay Relay (TDR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Rating:\u003c\/strong\u003e SPDT (Single-Pole Double-Throw)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelay Timing:\u003c\/strong\u003e Fixed Off-Delay (approx. 60 seconds)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 0.3 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ \u003cstrong\u003eHVAC Depot Pro Tip: The \"Blower-Only\" Test\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cp\u003eIf your outdoor compressor turns on but your indoor fan never starts, or if the fan turns off the second the compressor stops, the B1370738 is a likely culprit.
