Our take
Consider Hamilton Beach 31139 for a simple manual Toast, Bake, and Broil routine with a documented household electrical basis. Its four-slice and 9-inch-pizza references come from Newegg, and the sources leave the actual cavity and counter footprint unknown.
Newegg lists four slices or a 9-inch pizza; check the actual cookware because the guide gives no measured opening..
Not for Air Fry, Convection, Rotisserie, Keep Warm, measured pan fit, a full temperature span, numeric exterior clearance, or a guaranteed 30-minute automatic shutoff.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The guide documents separate Toast, Bake, and Broil procedures.
- A grouped rating table explicitly names 31139 at 120 V / 60 Hz / 1,050 W.
- Two manual controls make the toast shade and oven function easy to identify.
What to weigh up
- The 9-inch pizza and four-slice fit claims are retailer-reported.
- The guide gives no external clearance, exterior dimensions, or measured pan opening.
- Newegg's 30-minute automatic-shutoff claim is not confirmed by a manual timer limit.

What the features mean for you
The guide keeps cooking to three familiar modes
Hamilton Beach's shared guide documents Toast, Bake, and Broil for 31139. Toast uses the upper rack and a combined shade and timer control, with a bell at the cycle end. Bake uses the lower rack or pan after a five-minute preheat; Broil uses the upper rack with the pan below and calls for turning food partway through. That routine suits a buyer who wants ordinary manual cooking jobs. The guide does not describe Air Fry, convection, rotisserie, or Keep Warm for this exact model.
Two dials separate function from toast shade
The panel has a Function/Temperature knob, a Toast Shade Selector/Timer dial, and an ON indicator. Bake and Broil can use a timed setting or Stay On, so a longer cycle requires attention to the manual control rather than an assumed timer shutoff. The guide advises against unattended Toast and Broil and gives a one-inch food-to-element gap. That is an internal cooking clearance, not room needed around the outside of the appliance. The full thermostat range and manual timer maximum are not stated.
Treat the pizza and timer numbers as seller claims
Newegg lists four slices, a 9-inch pizza, adjustable temperature, and a 30-minute timer with ready bell and automatic shutoff. The guide itself offers a pizza placement tip but gives no slice maximum, pizza diameter, measured cavity, or pan footprint. It also does not publish a numeric timer ceiling. Use the retailer figures as labeled model claims when considering a likely routine, but do not turn them into a hard fit or shutdown guarantee. A dish with tight clearance needs a direct size check.
The household electrical basis is unusually specific
The guide says household use only, shows a polarized plug, and its final model table explicitly includes 31139 with a 120 V / 60 Hz / 1,050 W group rating. The metadata also names 31136, so the saved audit relies on the table entry that lists 31139 rather than copying a nearby model's figure. No numeric side or rear spacing, exterior dimensions, weight, or under-cabinet approval is provided. The documented rating helps screen electrical needs, while physical placement still requires checking the unit and counter.
Keep related model numbers and old offers separate
Frozen rows 238 and 502 both carry the 31139 clue and share this model-level packet, but their historical ASINs remain separate and neither is tied to a current offer. Hamilton Beach 31339 is an Easy Reach roll-top model with a different code; its door design should not be transferred here. The inspected sources also do not establish a named finish or current seller package. Search the exact 31139 code when checking an offer, and compare the seller's unit details with the guide before buying.
What else to compare
Choose Toastmaster TTOB4 if the documented Defrost and Keep Warm routines and four-to-six-inch spacing matter more than a named pizza fit.
Before you buy
Does the manual confirm a 9-inch pizza?
No. Newegg reports a 9-inch pizza fit; the shared guide does not state a diameter or measured opening.

No. Newegg lists that timer claim, but the guide does not state a numeric maximum.
What electrical rating is listed for 31139?
The guide's grouped table names 31139 at 120 V, 60 Hz, and 1,050 W for household use.

The decision
Choose 31139 for its documented manual routines and explicit grouped rating when Newegg's fit claim is useful but not a measured requirement.
