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.

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.
