Swimables Air Flow Switch Compatible with Pentair Pool Heater Parts

Type: Replacement Air Flow Switch for Pentair Mastertemp and Sta-Rite heaters.
This Swimables unit is designed for direct compatibility with multiple Pentair Mastertemp models (400, 300, 200, 125 low NOx) and Sta-Rite heaters. It addresses the common AFS (Air Flow Switch) error that appears when the control detects insufficient airflow. The AFS is mounted on the heater control box and is typically replaced when diagnostics confirm a switch fault.
- Compatibility: Works with listed Pentair and Sta-Rite models.
- Error Resolution: Intended to resolve AFS error codes resulting from switch failure.
- Installation Note: Located on the heater control box; the manufacturer recommends qualified installation for heater-related issues.

This Pentair-branded replacement is an original equipment manufacturer (OEM) part intended to match factory specifications for Pentair heaters. OEM parts are typically used when maintaining original performance and fit. The product listing identifies it as an air flow switch replacement for relevant heater models, serving as a direct swap for units triggering flow-related fault codes.
- OEM Assurance: Designed to meet Pentair’s specifications for fit and function.
- Application: Replacement for heaters showing air flow or related electrical system faults.
- Service Tip: Verify model compatibility against the heater’s service manual or part number before purchase.
42001-0061s Pressure Switch Compatible Air Flow Switch by ToughAid

Type: Replacement Air Flow / Pressure Switch kit compatible with Pentair and Sta-Rite heater models.
ToughAid’s kit is marketed as compatible with multiple MasterTemp and Sta-Rite Max-E Therm models. It typically ships with the airflow switch plus hoses, screws, and clamps needed for installation. The vendor emphasizes resolving the AFS error code and notes the switch’s cross-reference numbers (42001-0061s, 42001-0059S).
- Kit Contents: Air flow switch, hoses, screws, and hose clamps included in internal packaging.
- Compatibility Range: Lists several MasterTemp and Sta-Rite models; cross-check model numbers prior to replacement.
- Diagnostic Use: Recommended when AFS error indicates a switch malfunction rather than airflow obstruction.
Wood Stove Fan With Magnetic Thermometer By Xmasneed

Type: Heat-powered stove fan for wood, pellet, or gas stoves.

This non-electric fan uses thermoelectric/thermal fins to convert heat from a stove’s surface into mechanical rotation, activating at around 212°F. It distributes warm air horizontally with a rated CFM of roughly 160–220, aiming to spread heat from the stove into the room more quickly than radiant heat alone. The unit includes fittings for mounting to an uneven fireplace pipe surface and a magnetic thermometer for temperature monitoring.
- Power Source: No electricity required; operates from stove surface heat.
- Mounting: Designed to attach to chimney pipes between approximately 6.1–6.88 inches in diameter; includes rings and thermometer.
- Noise: Manufacturer-specified <25 dB during operation.
Home Intuition Adjustable Magnetic Heat And Air Deflector

Type: Magnetic vent deflector for sidewall, ceiling, and floor registers.
Home Intuition’s adjustable deflector redirects heated or cooled air to improve room comfort and reduce hotspots. The device extends and retracts between 10″ and 16″ to fit a variety of registers and uses strong magnets to secure to metal vent covers. Constructed from transparent heavy-duty plastic, it aims for a low-profile look while redistributing airflow to reduce HVAC cycling and potential overworking of equipment.
- Adjustability: Extends 10″–16″ for different vent widths.
- Attachment: Heavy-duty magnets secure to metal vents.
- Design: Transparent material for a low-visibility installation.
Buying Guide: How To Select The Right Air Flow Heater Component Or Accessory
Choosing the appropriate part or accessory depends on whether you’re addressing an HVAC distribution need or replacing a heater control component. Below are key considerations across multiple perspectives.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Identify The System And Purpose
- Heater Or Stove vs. Forced-Air System: Air flow switches (AFS) are specific to pool/spa heaters and must match the heater model; vent deflectors and stove fans address room airflow and distribution for home HVAC and wood stoves.
- Problem Type: Fault codes or electrical diagnostics typically indicate a failed AFS; uneven room temperatures often call for deflectors or convection fans.
Compatibility And Fit
- OEM vs. Compatible Parts: OEM parts (e.g., Pentair) match factory specs and may simplify warranty or service expectations. Compatible/replacement kits may include additional hardware and can be less costly, but verify cross-reference numbers and model lists.
- Physical Fit: For switches, confirm part numbers and mounting location. For vent deflectors, measure register width and verify magnet placement and adjustability range.
Performance And Operation
- Activation Threshold: For heat-powered stove fans, note the temperature at which the unit begins spinning and the claimed CFM to estimate distribution effectiveness.
- Noise And Materials: Check noise specs for fans and material durability for deflectors if aesthetics or quiet operation matter.
Installation And Maintenance
- Professional vs. DIY: Electrical or heater control box work usually requires a qualified technician to ensure safety and correct diagnostics. Vent deflectors and stove fans are typically user-installable.
- Included Hardware: Replacement switch kits that include hoses, screws, and clamps reduce the need to source extra parts; verify contents before buying.
Durability And Environmental Considerations
- Material Quality: Polycarbonate or heavy-duty plastics resist cracking for vent deflectors; OEM switches use materials rated for heater environments.
- Operating Conditions: For chimney-mounted fans, confirm pipe diameter compatibility and evaluate exposure to high temperature cycles.
Cost-Efficiency Perspectives
- Energy Savings: Redirecting airflow with deflectors or improving heat distribution with a stove fan can reduce thermostat demand and cycle frequency.
- Repair vs. Replace: For error codes on heaters, diagnose whether airflow obstruction, sensor wiring, or switch failure is the cause—replacing a switch may not resolve problems due to unrelated airflow issues.
Comparison Checklist Before Purchase
- Confirm exact model numbers and part cross-references for heater switches.
- Measure vents/registers and confirm magnet attachment compatibility for deflectors.
- For stove fans, verify activation temperature and mounting fit for your chimney or stove surface.
- Check included installation hardware and whether professional installation is recommended.
- Read product documentation for troubleshooting tips and compatibility notes.
