Heil Quaker Parts - Furnace & AC
ICP Heil Quaker parts cover the replacement components for Heil and Quaker-branded HVAC equipment, from capacitors and control boards to fan parts and limit switches. The category groups parts by function to help technicians find the right component during a service call.
Limit switches in particular are safety devices that shut a furnace down before the heat exchanger overheats, so replacing a failed switch with the correct rated part matters for safe operation. Keeping common capacitors and control boards on a service truck reduces the number of return trips for routine failures.
Subcategories
- ICP Heil Quaker Capacitors: Run and start capacitors keep Heil Quaker blower and condenser fan motors starting and running at full speed. Technicians replace them when a motor hums but won't start, or when amp draw at the motor climbs above the nameplate rating, and matching microfarad rating and voltage to the original capacitor is the key spec to check before swapping one in.
- ICP Heil Quaker Control Boards: Control boards manage ignition sequencing, blower timing, and safety lockouts on Heil Quaker furnaces and air handlers, including boards such as the 1186024 and 1184408 used across multiple model years. Techs pull a board when a furnace won't cycle correctly, throws a fault code, or fails to bring the igniter or gas valve online in the right sequence, and matching the connector layout to the original board avoids a rewiring job.
- ICP Heil Quaker Fan Parts: Fan parts cover the blades, blower wheels, and fan mounting hardware that move air across the heat exchanger and coil in Heil Quaker equipment. Crews replace a blower wheel when it's cracked, unbalanced, or corroded enough to throw the airflow off, and matching wheel diameter, width, and bore size to the original part keeps airflow and static pressure where the equipment was designed to run.
- ICP Heil Quaker Limit Switches: Limit switches shut a furnace down before the heat exchanger overheats, tripping when plenum or discharge air temperature climbs past a set point. Technicians replace a limit switch when a furnace short cycles on heat or won't start at all, and matching the switch's trip temperature and mounting bracket to the original part keeps the safety cutoff working at the temperature the furnace was designed around.
- ICP Heil Quaker Miscellaneous Parts: Miscellaneous parts round out the category with the smaller components that don't fit neatly elsewhere, including gaskets, wire harnesses, transformers, and mounting brackets specific to Heil Quaker equipment. Techs turn to this group when a repair needs a small hardware or wiring piece rather than a major component, and cross referencing the original part number is still the fastest way to find the right fit here.
- ICP Heil Quaker Motors & Parts: Motors & Parts covers the blower and condenser fan motors that move air through Heil Quaker furnaces, air handlers, and air conditioners, along with motor mounts and related hardware. Crews match a replacement motor by horsepower, RPM, rotation direction, and frame size, since a motor that's electrically similar but mismatched on any one of those specs won't move the air the equipment was designed to move.
Buying Guide
Identifying an ICP Heil Quaker part starts with the model and serial number tag on the equipment cabinet, not the part that looks similar in a catalog photo. Because Heil Quaker shares tooling with Arcoaire, Comfortmaker, KeepRite, and Tempstar, the nameplate data often cross references to a part number sold under more than one of those brand names, so pulling the exact number from the equipment or the failed part itself avoids ordering the wrong one.
Control boards carry the most model specific variation in this lineup, since ignition sequence, blower staging, and diagnostic codes differ across furnace generations even within the Heil Quaker family. Matching the board's connector count, mounting hole pattern, and terminal labeling to the original, rather than assuming any board with the right general description will work, prevents a board that powers up but won't run the furnace correctly.
Capacitors and motors are usually the fastest calls to close out, since they're defined by a small set of electrical specs: microfarad rating and voltage for capacitors, horsepower, RPM, and rotation direction for motors. Keeping the common sizes for the equipment most active in a given service area on the truck turns a same day diagnosis into a same day repair.
Limit switches and other safety controls need to match trip temperature exactly, since a switch set to trip too high defeats the purpose of the safety circuit and a switch set to trip too low causes nuisance shutdowns. Cross referencing the stamped temperature rating on the failed switch against the replacement, rather than swapping in any switch that physically fits the mounting bracket, keeps the safety function intact.
For parts that fall into the miscellaneous category, such as gaskets, harnesses, and brackets, physical fit matters as much as any electrical spec. Comparing dimensions and connector types side by side with the failed part before ordering saves a second order when a part that's technically the right function turns out to be the wrong size.
Frequently Asked Questions
Are ICP and Heil Quaker parts the same as Arcoaire, Comfortmaker, and Tempstar parts?
Often, yes. These brands are built by the same manufacturer and frequently share identical control boards, motors, and capacitors across model generations. Confirming the exact part number stamped on the failed component is more reliable than matching by brand name alone.
Why won't a furnace fire even after replacing the control board?
A furnace can still fail to fire after a board swap if the new board's connector layout or staging sequence doesn't match the original, or if a separate component such as the igniter, gas valve, or limit switch is also faulty. Checking the full ignition sequence against the equipment's wiring diagram after any board replacement rules out a second failed part.
How do I tell if a capacitor has failed on a Heil Quaker blower motor?
A motor that hums without starting, starts slowly, or runs hot and shuts off on overload often points to a failed run or start capacitor. Measuring the capacitor's microfarad rating against the value stamped on its case confirms the failure before ordering a replacement.
What causes a Heil Quaker furnace to short cycle on heat?
A tripped limit switch is a common cause, usually from restricted airflow, a dirty filter, or a blower running at the wrong speed for the heat output. Replacing the limit switch only fixes the symptom if the underlying airflow restriction is corrected at the same time.
Can a universal blower motor replace an OEM Heil Quaker motor?
A universal motor can work as a replacement when its horsepower, RPM, rotation direction, and frame size match the original motor exactly. Mounting hardware and shaft length also need to line up, since Heil Quaker equipment cabinets are often built around the original motor's physical dimensions.
