Goodman Rollout Switch

A furnace limit switch (also called a high limit switch or fan limit switch) is a safety and control device that monitors the air temperature inside the furnace. It ensures the furnace operates safely by: Turning the blower fan on and off at the right temperatures. Shutting off the burners if the furnace overheats. Essentially, it prevents damage to the furnace and protects against fire hazards caused by excessive heat.

60 Amp Air Conditioning Disconnect

The Eaton G8064 is a non-fusible pull-out disconnect device designed for air-conditioning and heat-pump condensing units. It provides a visible means of disconnect (you can physically pull out the module to disconnect power) so that service technicians have a clear “off” state for maintenance. It is housed in a weather-resistant outdoor enclosure (typically NEMA 3R rain-proof) making it suitable for wall-mount near an outdoor A/C unit. According to one distributor:

Furnace Air Pressure Switch

A furnace pressure switch is a safety and control device that monitors air pressure (often negative or slight vacuum) in the furnace’s venting / flue / inducer system to ensure proper airflow before allowing ignition. If the airflow (draft) is insufficient — due to blocked venting, faulty inducer motor, or leaks in tubing — the pressure switch will prevent the furnace from igniting or will shut it down mid-cycle. It is typically mounted near the inducer motor or in the blower compartment. It connects via small flexible tubing to sense pressure (vacuum or slight positive pressure) created by the inducer blower. Its internal mechanism (diaphragm, spring, contacts) responds to changes in pressure, opening or closing electrical contacts in the furnace control circuit. In many furnace systems, the control board uses the switch’s state (open/closed) as a gating condition: the blower must achieve the required pressure before ignition is permitted. (If the pressure switch does not close, the furnace will lock out for safety.) How to Choose Best HVAC Systems +3 A. O. Smith +3 Aire Serv +3 Because this part is in the safety chain, it must be correctly rated and matched to the furnace’s required pressure setpoints (i.e. the specific “close on vacuum” value). Thus, the pressure switch helps prevent combustion gases (e.g. CO) from being forced into the living space when venting is blocked or compromised.

SUPER BOOST Relay & Hard Start Capacitor

A “Super Boost” relay + hard start kit (often under Supco’s Super Boost / SPP series) is an accessory used with single-phase compressors (especially in HVAC systems) to assist the compressor during startup. The kit typically combines: A start capacitor sized to give extra starting torque, and A relay or PTC / EPR (Positive Temperature Coefficient / Electronic Potential Relay) to remove the start capacitor from the circuit once the compressor is up to speed. The purpose is to help “hard start” or “weak start” compressors, especially under low-voltage conditions or when the motor is under load (e.g. high ambient temperature). The Super Boost kits are marketed to provide high torque boost (for example “500 % torque increase” in some models). Edmondson Supply +2 supco.com +2 They are designed for “two-wire” installation (across the run capacitor terminals) in many PSC (permanent split capacitor) motors, and are UL-recognized.
