What it is
The Halstead 988301 is an electronic aquastat supplied complete in its housing assembly. It is a temperature-sensing control used on Halstead Best boilers, where it monitors water temperature and feeds that signal back to the boiler control circuit. The assembly is a direct replacement for the factory-fitted unit of the same part number.
Signs this part needs replacing
- The boiler fails to reach or hold the temperature set on the control
- Heating output runs on when it should have modulated down or shut off
- Domestic hot water temperature swings noticeably between draws
- The boiler locks out or logs a temperature-related fault
- The boiler trips on its overheat protection during normal running
Before you order
- Check the appliance GC number against the compatibility list; the Best range is covered by the 41-333-xx numbers listed there.
- Confirm the number on the existing unit. 988301 is also listed under 1294110 and the earlier 600513.
- Inspect the housing and any sealing washer when the old assembly is removed, and renew the seal if it is perished or deformed.
