Fryer Thermostat Parts Reference is a free, non-commercial reference index of commercial deep-fryer part numbers — thermostats, hi-limits, heating elements, gas valves, ignition modules and thermopiles — compiled for buyers, maintenance technicians and parts distributors who need to identify a discontinued part and find its current cross-reference. Nothing here is for sale, and no price on this site is ours to honour; the value is the identification data and the source trail behind it.
Reference compilation of commercial deep-fryer part numbers, interchange cross-references and compatible fryer models. Indexed: 7 thermostat / hi-limit families (80 part numbers), 6 gas-valve / ignition / thermopile families (52 part numbers) and 3 heating-element families.
Thermostat families in the index run 200–400 °F with nickel bulbs from 1/4 in to 3/8 in and capillaries of 24 in, 48 in or 96 in; hi-limits cut out at a fixed 450 °F. Element families are indexed by voltage and wattage — 240 V / 5500 W, 8500 W and 12000 W assemblies — because the same physical element is supplied under separate part numbers for 208 V, 240 V and 480 V.
“Interchange numbers come from distributor tables, not from manufacturer statements. They are recorded as reported, not verified. Treat them as leads.”
As stated in the compilation notes, where two sources disagree the disagreement is recorded rather than silently resolved — for example a 24 V gas-valve regulator set point published as both 3.0 in WC and 3.5 in WC.
Two things buyers ask that a part-number page cannot answer: how this parts market actually works, and whether one part can replace another.
Commercial fryer heating elements are normally selected by voltage and wattage before the part number is confirmed. The element families currently indexed:
