Janitrol Serial Number Lookup

Decode the serial number from the data plate. The dominant Janitrol format (1982 to 1992) is: 10 digits; digits 1-2 = year, digits 3-4 = month. Example: 9104011000 decodes to April 1991 (Janitrol). Subtract the decoded year from the current year for the age.

Janitrol shares its serial number FORMAT with Goodman, Amana, and Daikin, so one decode rule reads the date on all of them. That is a format match and nothing more. Refrigerant era and warranty terms are per brand, and this page states Janitrol's own.

Goodman family 10-digit (YYMM): Checked against 10 serials whose date a recall notice published by someone other than us states (CPSC recall notice 08-602, CPSC recall notice 17-103, CPSC recall notice 18-113, CPSC recall notice 22-021), 4 of them air handlers, models AWUF and ACNF, across 4 equipment types. The date this tool reads first was consistent with the published window on all 10. Also read against 53 serials where a public body's own equipment schedule prints a year beside the serial (Norcross, Georgia; Winter Park, Florida; the year sits under a column headed Year, which the document does not define), 24 of them condensing unit, across 10 equipment types: 51 matched the reading shown first, 2 did not match any reading (the published year ran later than this tool's reading on all 2); and 2 serials where a seller entered a year in the listing's own year field on a government surplus listing for the serial (government surplus auction listings), 1 of them CAPF4961C6DB coil in two-unit lot, across 2 equipment types: 2 did not match any reading (the published year ran later than this tool's reading on all 2); a seller's year is shown here for the record and is not counted toward this format's check.

Across the Janitrol format on this page, 15 serials with a date published outside this tool produced no reading at all (Winter Park, Florida; Norcross, Georgia). A serial this tool reads nothing from is neither an agreement nor a disagreement, so it is counted in neither.

Where someone outside this tool wrote down a different year for a unit, that year is shown here rather than dropped. It is that publisher's record for the unit, and a schedule or a listing can carry a replacement, system or lot year rather than the build year. The MFG DATE on the unit's data plate is the build date.

By manufacture year: through 1992: R-22. The refrigerant printed on the nameplate is authoritative; the year-based mapping tells you what is typical for the age, not what is in a specific unit.

No page of Janitrol's own for looking up a warranty is linked here, and this page does not read any maker's records, so it cannot show whether a unit was registered. Enter the serial in the lookup on this page for the build date and the unit's age. No Janitrol warranty certificate is held here for a dated term, so the result dates no term, says so, and names what would answer it; a Service Brief carries what is known to whoever works on the unit. One U.S. Consumer Product Safety Commission recall notice this tool matches names Janitrol equipment. Where the serial and model entered meet, or may meet, a notice's printed conditions, the result shows that notice first, with CPSC's own hazard and remedy, and compares each condition; where a notice lists models and none was entered, it asks for the model, unless something else entered or read from the serial rules the unit out of that notice. It never says a unit is or is not recalled, and it says nothing when nothing entered meets or may meet one.

The brand was retired in 1992. No Janitrol warranty certificate is held here, so this tool states no term for a Janitrol unit. The result does not work out a dated term for Janitrol: no Janitrol certificate is registered for that here. Only the maker's records show whether a unit was registered.

Janitrol was retired in 1992; every Janitrol unit is 30+ years old. This matches a pre-mid-1980s Janitrol style. This tool holds no decode key for it, and the unit is 40+ years old either way.

No maker document held here dates Janitrol furnaces, so the tool does not call a date a Janitrol furnace's age; it reads the serial by the same rule it uses for Janitrol's other equipment.
