Control modules for refrigeration defrost cycles ensure precise timing and sequencing to protect product quality and maintain energy efficiency. This defrost fan delay control delays fan operation after defrost, reducing heat exchange and preventing compressor short-cycling for steady performance. The compact module measures 5.55 x 7.65 x 1.85 inches and weighs 0.42 pounds, making it easy to mount in tight spaces.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe high-touch surfaces—menu covers, shakers, chair backs, and door handles—with a neutral detergent, then disinfect per label directions. Clean booth crevices and under shelves to remove crumbs and spills that attract pests. Dry surfaces fully to prevent material damage. Inspect regularly and re-clean between shifts to maintain customer perception and stay compliant with health codes.#@@#Additional Info#@#PartsTown MB19-00890 control (19-00890) measures 5.55 x 7.65 x 1.85 inches, weighs 0.42 lbs, offers timed defrost-fan sequencing for commercial refrigeration, and is compatible with inventory and service applications.#@@#General Info#@#Description #@#
Control modules for refrigeration defrost cycles ensure precise timing and sequencing to protect product quality and maintain energy efficiency. This defrost fan delay control delays fan operation after defrost, reducing heat exchange and preventing compressor short-cycling for steady performance. The compact module measures 5.55 x 7.65 x 1.85 inches and weighs 0.42 pounds, making it easy to mount in tight spaces.
#@@# Delay Sequencing#@#
The unit enforces a controlled fan restart interval after defrost, preventing warm air recirculation and maintaining stable temperatures. This reduces temperature recovery time and protects chilled inventory from thermal shock.
#@@# Compact Envelope#@#
The small footprint fits constrained housings, leaving room for adjacent controls and wiring. Its low-profile design simplifies retrofits and minimizes cabinet modifications during replacements.
#@@# Precise Timing#@#
The control provides deterministic delay characteristics that integrate with defrost cycles for consistent operation. Technicians can rely on repeatable timing to diagnose system behavior and validate performance.
#@@# Service-Friendly Weight#@#
Weighing 0.42 pounds, the module is easy to handle during installation and service, reducing strain in crowded evaporator compartments. Its light weight also simplifies inventory and shipping logistics.
#@@# Manufacturer Traceability#@#
PartsTown supplies this part under part number MB19-00890, with internal identifier 19-00890, enabling straightforward ordering and cross-referencing. Procurement teams can match it to service records and parts lists with ease.
#@@# Application Fit#@#
Designed for commercial refrigeration systems, this control suits foodservice, institutional, and hospitality operations requiring reliable defrost management. Its classification within parts inventory channels helps maintenance planners locate compatible components for routine repairs.
