What to Verify Before Ordering

These are the points that most often cause a wrong order on this specific part number. They are not generic advice.

Reset type is MANUAL, not auto — LCH hi-limit, fixed 435 F, manual reset. The auto-reset LC117 (00-419670-00001) is a different device with a different set point - do not substitute one for the other.
Fixed set point — 435 F fixed; there is no adjustment. A 450 F unit is a different part number.

Compiled from manufacturer catalog strings and distributor listings. Verify against your own equipment's parts manual before ordering. This is not an offer or a quotation.

As the OEM parts catalog lists it

Hobart's own catalog lists this hi-limit on the heating-element assembly page, not in a generic thermostat section. According to FORM 43124 Rev. A (February 2009), the entry reads “00-414146-00002 Thermostat Hi-Limit” with a quantity of 1, on the same page as the element assemblies it protects.

Source: Hobart, Catalog of Replacement Parts — 1HF Series Fryer, FORM 43124 Rev. A (February 2009), Heating Element Assembly, p. 15 (illustration for 1HF50C/D and 1HF85C/D). Retrieved 2026-10-27: https://www.wasserstrom.com/wcsstore/WasserstromCatalogAssetStore/Attachment/Hobart-parts.pdf. Quoted under fair use for identification; the manual is the publisher's document.

The catalog does not print a reset type or a set point against the line. Those values on this page come from the device marking and distributor data, not from this document.
Being on the element-assembly page is the useful part: it fixes which fryers the part is listed for (1HF50C/D, 1HF85C/D) and that there is one per element assembly.

What it fits and where it is used

High-limit safety device on Hobart 1HF series fryers and as second-stage high-limit protection on Vulcan EEF/REF/SPE/SPER fryers. Manual reset: it must be reset by hand after tripping, which ensures the fault is investigated.

What it does and how it fails

A fixed-set-point safety switch with its own sensing bulb. It does not control temperature: it removes the circuit when the sensed temperature passes a limit the appliance must not exceed. This one is manual reset — once it opens it stays open until a person presses the reset button, which is the point: somebody has to look at the fryer before it runs again.

Symptom check — is this hi-limit, manual reset the cause?

Symptom	This part?	Check first
Fryer dead after an overheat event, pilot or ignition fine	Yes — the device is open	On a manual-reset unit press the button once; then find the cause before running a service
Trips again within a service cycle	No — it is doing its job	Oil level, coated bulb, blocked flue, ventilation, gas-valve overfiring, control thermostat not cycling
Oil smokes or smells burnt before it trips	No	Control thermostat calibration or a mis-seated control bulb
Trips with cold oil at start-up	Possible — wrong set point, or a failing device	Compare the stamped cut-out with the appliance manual and check the wiring holding the circuit

How to test it before you replace it

Isolate power and gas, and let the oil cool.
Measure continuity across the two terminals: closed means the device is intact. On a manual-reset unit that reads open, press the reset button once and measure again — it should close with an audible click.
Heat the bulb and confirm it opens at its stamped cut-out (435 °F), then cool it. A manual-reset device must stay open until pressed; an auto-reset device must reclose on its own. If it does neither, the device has failed.
Clean the bulb before refitting. A coated or loose bulb senses a cooler temperature than the oil and delays the cut-out — the failure mode that lets oil reach its flash point.
Confirm the replacement matches cut-out, reset type, bulb (1/4 in × 4-7/8 in, nickel) and capillary (24 in) — all four, not just the thread.

These are standard electrical and gas-side checks for the device family, not a service manual for your fryer. Work with the appliance isolated, and have gas-side work done by a qualified fitter. Where this page states a value, it is copied from the specification table above; where it does not, the reading is only meaningful against your appliance manual.

Substitutions that fit but do not work

Auto reset instead of manual reset. The most common and the most dangerous substitution on a fryer: the appliance restarts itself after an overheat, the fault repeats unobserved, and the next event is worse.
Set point. 435 °F (fixed) on this record. A higher cut-out removes margin; a lower one trips during normal cooking and gets bypassed by the next technician.
Bulb and capillary. Same thread, different sensing length: the device then reads a different part of the well and cuts out at the wrong oil temperature.

Frequently Asked Questions

What does 00-414146-00002 fit?

Hobart 1HF series fryers (1HF50D, 1HF50C, 1HF85C, 1HF85D) — it appears in the Hobart 1HF series parts manual — and Vulcan EEF/REF/SPE/SPER fryers as second-stage high-limit protection.

Is it manual or auto reset?

Manual reset, with a fixed 435 °F cut-out.

What is the difference between LCH and LC117 hi-limits?

Both are safety cut-outs, but they are different part families with different cut-out temperatures (435 °F for LCH vs 450 °F for LC117) and reset behaviour.

China Sourcing Notes

Capillary, millivolt and high-limit thermostats in these part families are produced in volume in China. Public supplier directories list manufacturers concentrated in specific industrial clusters: Zhongshan (Guangdong) for capillary, millivolt and deep-fryer thermostats; Wenzhou (Zhejiang) for capillary, gas, immersion and mechanical thermostats with OEM/ODM capability; and Jinan (Shandong) for gas-valve and thermostatic gas-control components. When sourcing these parts from China, verify: dimensional drawings, sensing-bulb and capillary specifications, temperature accuracy, electrical ratings, cycle-life testing and applicable safety certifications (CE / CQC / UL). A high-limit safety thermostat must not be substituted on the basis of physical fit alone.
