When a commercial ice machine won't hold temperature or a Hoshizaki unit starts acting up, the fix often comes down to one replacement part. The challenge is that foodservice parts components cover very different jobs: controllers manage the electronics, strainers protect water lines from debris, and bearings keep moving parts operating smoothly. The first step is to identify which failure you are dealing with, then match it to the right component.
Quick take
All four parts are listed as New, but they split into three distinct repair categories. The two Hoshizaki controller replacements handle control-system failures. The Hoshizaki 5/16-inch strainer manages debris. The TRUE roller bearing with mounting stud is for mechanical wear in TRUE equipment. Listed prices range from $32.29 to $184.55, so the product you order should be driven by the repair you are doing rather than the part with the lowest list price.
Listed prices at a glance
The table below shows the listed price for each part, with a relative bar to show how the costs stack up.
| Product | Listed price | Listed price bar |
|---|---|---|
| Hoshizaki SP-5764 Ascon UR/WR Controller Replacement | $184.55 | |
| Hoshizaki SP-5766 Controller Replacement | $182.91 | |
| Hoshizaki 441569-04 Strainer 5/16" Filters Debris | $32.29 | |
| TRUE 844597 Roller Bearing With Mounting Stud | $85.05 |
Decision matrix
| Part | Best matched to | Consider if |
|---|---|---|
| Hoshizaki SP-5764 | Ascon UR/WR controller replacement | Your Hoshizaki unit needs the UR/WR controller function |
| Hoshizaki SP-5766 | Ascon SR controller replacement | Your Hoshizaki unit takes the Ascon SR controller |
| Hoshizaki 441569-04 | Debris filtering in Hoshizaki equipment | You want to keep contaminants out of the water path |
| TRUE 844597 | Roller bearing with mounting stud | A TRUE appliance needs a mechanical bearing replacement |
Product notes
Hoshizaki SP-5764 Ascon UR/WR Controller Replacement Commercial Appliance Parts
If your Hoshizaki unit uses an Ascon UR/WR controller, this genuine Hoshizaki replacement supplies the controller needed to keep the system operating. It is designed for Hoshizaki commercial appliances and uses a simple installation process when the original part fails. Because it is a controller, it speaks directly to the electronics side of the machine: the part that regulates settings and keeps the unit on track. Choose it when the failed component matches this UR/WR spec. The limitation is that it is a controller-only component. It will not remove debris from the water path, and it will not correct a mechanical bearing that has worn out. If your diagnosis points to a different failure, this part will not solve it.
Hoshizaki SP-5766 Controller Replacement Commercial Appliance Parts
The SP-5766 controller replacement is the companion part for Hoshizaki units that take an Ascon SR controller. It is a genuine Hoshizaki part for commercial refrigeration equipment and is built for precise management of refrigeration settings. If the controller failure is making your unit run poorly in the refrigeration cycle, this replacement is the direct match for that repair job. It is also simple to install, which keeps the swap focused on the part itself rather than surrounding components. The limitation is that it is still a controller-level replacement. It will not filter water, and it has no role in mechanical parts like bearings or rollers. Use it when the controller is the confirmed issue.
Hoshizaki 441569-04 Strainer 5/16" Filters Debris Commercial Appliance Parts
This strainer is the debris-handling part in the group. It fits into Hoshizaki equipment to filter unwanted debris and contaminants, helping prevent clogs from interfering with water flow. Because it is a small component, it is a strong candidate for scheduled maintenance. Choose it when particulate buildup is the suspected cause of weak flow or when you are refreshing the water path. Its tradeoff is that it handles debris, not electronics or mechanics. A failing controller or worn bearing is outside its job description. If your machine's problem is not water-related, this strainer will not address the root cause.
TRUE 844597 Roller Bearing With Mounting Stud Commercial Appliance Parts
The TRUE 844597 is a roller bearing with a mounting stud, made for commercial appliances that use this style of component. It supports smooth operation and prolongs equipment life, which makes it the part to consider when a worn bearing is affecting how smoothly the equipment moves. The mounting stud is part of the replacement package, so you are getting the bearing and the mounting point together. Choose it when the diagnosis points to mechanical wear rather than an electrical or water-line issue. The limitation is the opposite of the strainer: it addresses mechanical wear only, and it will not help with debris or controller failures.
Final recommendation by use case
- For a Hoshizaki unit that needs an Ascon UR/WR controller, the SP-5764 is the part to order.
- For a Hoshizaki unit that needs an Ascon SR controller, the SP-5766 is the matching replacement.
- For preventing debris-related clogs in Hoshizaki equipment, the 441569-04 strainer is the part that fits that job.
- For a worn TRUE roller bearing with mounting stud, the 844597 is the mechanical replacement to choose.
Match the part to the failure rather than choosing by list price alone. That gives you the quickest path back to normal foodservice operation.
