Crathco Repair · Bay Area

Crathco builds cold and frozen beverage dispensers for convenience stores, cafes, and concession stands. Grindmaster and Welbilt sit behind the brand. We service the Crathco D line, the FROZEN and Mini-Pro units, and the bubbler and spray models. When one of these goes down on a hot afternoon, you lose sales by the hour, so we work to get it back online the same visit when parts allow.

The most common call is a magnetic drive coupling that has worn or lost its grip. The auger stops turning, product separates in the bowl, and the unit looks dead even though the compressor still runs. We pull the bowl, check the drive magnet and the coupling, and replace what is worn. Agitator and auger motors fail the same way after years of duty, and we swap those out when the bearings or windings are gone.

Refrigeration faults are the other big bucket. A weak evaporator, a bad cold plate, or a unit that freezes the product solid all point to the sealed system or the controls. We test the refrigeration side, check the cold plate, and trace the fault before quoting. Sealed-system and refrigerant work is licensed under CSLB #1136642, so it is done right and to code, not patched.

Then there are the leaks and the seals. Bowl gaskets, shaft seals, and worn O-rings let product weep down the front or into the base. Left alone they ruin bearings and breed bacteria. We replace the gasket and seal kits and clean up the drive path while we are in there.

Almost always worth repairing

A Crathco dispenser is a workhorse, and the failures above are wear items, not the end of the machine. A coupling, a motor, a seal kit, or a refrigeration repair costs a fraction of a new unit, and the cabinet and compressor usually have plenty of life left. For a commercial operator, the math is simple. Downtime and a replacement bowl cost more than the fix on nearly every one of these.

We charge a flat $75 diagnostic, waived when you book the repair. You get a written quote before any work starts, so there are no surprises on the invoice. If a unit is genuinely past saving, we tell you straight and you decide.

Call ADRIUM

From a recent job

We diagnosed a no-cooling fault on a Crathco cold beverage dispenser at a Millbrae restaurant and traced it to a failed R290 compressor from a known manufacturer bad-batch, so the unit went back under factory warranty instead of a paid repair. A few photos from that visit:
