Job card: pizzeria prep table not holding temperature with a hot compressor; condenser packed with flour and dough and the fan motor seized; Weiguang YZF10-20 motor replaced, coil cleaned, product verified at 39.9 degrees

Pizza prep table not holding temperature, compressor hot to the touch.

Open condensing section of a prep table with dough scraps and flour packed around the compressor and condenser coil

Pull the grille and this is the condensing section: dough scraps, flour, and a fan that had stopped turning. In a pizzeria, flour goes airborne all day. The condenser fan pulls it in and it packs into the coil fins like felt. The coil can’t reject heat, the fan motor runs hot against the restriction, and eventually the motor gives up.

Left, dough and flour debris inside the prep table condenser section; right, a new Weiguang YZF10-20 condenser fan motor

The motor is a Weiguang YZF10-20, a 120-volt shaded-pole condenser fan motor. A cheap part doing an important job. New motor in, coil cleaned out, compressor back to a normal temperature.

Left, a thermometer on the prep table reading 73.5 in the kitchen and 39.9 in the product zone; right, the prep table display reading 40

Then the check that actually matters: a thermometer in the product zone. Display read 40, product at 39.9, kitchen at 73.5. Working.

What to do about it: the condenser coil on a prep table in a pizzeria needs brushing out monthly, not yearly. It’s a five-minute job with the grille off. The fan motor was cheap. A prep table full of spoiled product is the number nobody wants to write down.
