What it is
The Gledhill GT188 is a boiler overheat thermostat supplied as a manual set for the Gulfstream 2000 appliance. It monitors boiler temperature and cuts the burner when the set limit is exceeded, protecting the appliance from overheating. Once tripped, the cut-out is reset by hand.
Signs this part needs replacing
- The boiler locks out repeatedly and requires a manual reset each time
- The overheat cut-out trips shortly after the appliance fires
- The reset button feels loose, seized or fails to latch
- Boiler temperature climbs past the normal operating range before the cut-out operates
- The appliance runs for a short period, then shuts down on overheat with no other fault indicated
Before you order
- Confirm the appliance model is the Gledhill Gulfstream 2000
- Check the part number on the existing thermostat against GT188
- Confirm the existing thermostat is a manual reset type
- Inspect the wiring and connections at the thermostat before replacing it
