Robertshaw Parts

Robertshaw parts cover the gas valve testing equipment, heat pump controls, and ignition components used to service Robertshaw-equipped heating and cooling systems. The category also includes limit controls, switches, and thermostats built for Robertshaw applications.

Gas pressure test kits in this category let technicians verify inlet and manifold pressure during a service call, a routine check on gas-fired equipment. Ignitor kits pair a hot surface or spark ignitor with the components needed for a complete ignition system replacement.

Subcategories

  • Robertshaw Gas Pressure Test Kits: Gas pressure test kits check inlet and manifold pressure on furnaces and other gas-fired equipment during startup and service work. Technicians use them to confirm a gas valve or regulator delivers correct pressure before completing an installation or troubleshooting a combustion complaint. The kits typically include a manometer along with fittings for common test ports.
  • Robertshaw Heat Pump Controls: Heat pump controls manage defrost timing, reversing valve operation, and staging between compressor and auxiliary heat on heat pump systems. Contractors replace these boards when a heat pump short-cycles, fails to defrost properly, or won't switch between heating and cooling modes. Matching the control to the original board's terminal layout and voltage rating keeps the wiring straightforward.
  • Robertshaw Ignitor Kits: Ignitor kits pair a hot surface or spark ignitor with the bracket and wiring harness needed for a direct replacement on gas furnaces and other ignition-controlled appliances. A worn or cracked ignitor is one of the most common reasons a furnace fails to light on a cold call. Confirming ignitor type and mounting pattern against the original part avoids a mismatch during installation.
  • Robertshaw Limit Controls & Switches: Limit controls and switches shut down burner or blower operation when a furnace or boiler exceeds a safe temperature threshold, protecting the heat exchanger from damage. Technicians replace these when a unit trips on high limit repeatedly or fails to restart after a lockout. Temperature setpoint and switch action, whether open or closed on rise, need to match the original part.
  • Robertshaw Miscellaneous Parts: Miscellaneous parts cover smaller components such as relays, transformers, and sensors that don't fall under a single dedicated control category but still keep HVAC and appliance systems running. Technicians stock these for spot repairs where a single failed component, rather than a full control board, is causing the equipment fault. Cross-referencing the original part number helps confirm compatibility before ordering.
  • Robertshaw Thermostats: Thermostats in this lineup include gas, electronic, and wall-mounted models used to control temperature setpoints on furnaces, boilers, and other heating equipment. Contractors select between mechanical and electronic versions based on the equipment's existing control wiring and the level of temperature precision the application calls for. Replacing a failed thermostat with a matching voltage and switching configuration restores normal cycling.

Buying Guide

Identifying which system function has failed, whether ignition, defrost timing, limit protection, or thermostatic control, is the starting point for choosing the correct Robertshaw replacement part, since each product line serves a distinct role in HVAC and appliance equipment.

Electrical ratings matter as much as function. Voltage, current draw, and number of switch poles or relay outputs need to match the equipment's original specifications, since an incorrect rating can cause nuisance trips or leave a load unpowered.

Ignition components require attention to type. Hot surface and spark ignitors are not interchangeable, and mounting brackets vary across furnace models, so confirming the original ignitor's mounting pattern and voltage before ordering prevents a return trip.

Limit controls and heat pump controls depend on the temperature setpoint and switching action built into the original part. A replacement with the wrong setpoint can cause a furnace to trip prematurely or fail to shut down when it should, so checking the stamped setpoint on the old control is worth the extra minute.

Contractors stocking Robertshaw parts benefit from cross-referencing a failed component's original part number and wiring diagram rather than shopping by product name alone, since several boards in this lineup share similar functions but serve different equipment types.

Frequently Asked Questions

What types of parts does Robertshaw make for HVAC equipment?

Robertshaw manufactures electromechanical controls and valves including gas thermostats, ignition modules, heat pump controls, limit switches, and pressure test kits used across furnaces, heat pumps, and other HVAC and appliance equipment.

How do I know if a furnace ignitor needs to be a hot surface or spark type?

Ignitor type is set by the furnace design, so checking the original ignitor before ordering a replacement is the fastest way to confirm whether the system uses hot surface or spark ignition. Mounting bracket and voltage should also match the original part.

What's the difference between a limit control and a heat pump control?

A limit control shuts down burner or blower operation when equipment exceeds a safe temperature threshold, protecting the heat exchanger from damage. A heat pump control instead manages defrost timing, reversing valve operation, and staging between compressor and auxiliary heat.

Why would I need a gas pressure test kit?

A gas pressure test kit lets a technician confirm that a gas valve or regulator delivers correct inlet and manifold pressure during startup or troubleshooting. Confirming pressure before completing a repair helps rule out combustion problems tied to gas supply.

Are Robertshaw thermostats compatible with any furnace or boiler?

Thermostat compatibility depends on the equipment's existing control wiring and required switching configuration, so matching voltage and switch action to the original thermostat is necessary before installing a replacement.
