Nordyne 626552R Fan Switch the 8402-067BX offers improved reliabilityThis Nordyne 626552R Fan Switch is the direct engineering update for the legacy 626552, designed specifically for high reliability HVAC blower motor control. As an OEM Nordyne part with an F115 20 technical designation, it functions as a normally open (NO) switch that closes upon reaching 115F and maintains a 20F differential.
