Specifications

  • Type: Heat Only Thermostat
  • Dimensions: 4.15"x 3.6"x 2.05"

Product Overview:
Dedicated heating control regulates indoor temperature in furnace applications that require heat-only operation. The York S1-025-38252-000 Heat Only Thermostat is a genuine OEM replacement thermostat designed for selected York and Coleman heating equipment. Its two-wire control arrangement supports basic heating operation, allowing the furnace to respond to the room temperature setting.

Heating Temperature Control:
A temperature-sensitive control monitors room conditions and signals the heating system when the temperature falls below the selected setting. The heat-only configuration is intended for applications that require heating control without separate cooling operation.

Two-Wire Connection:
Thermostat uses a two-wire connection to control heating operation in supported furnace applications. This wiring arrangement communicates the heating demand between the thermostat and furnace. Match the existing terminal connections and wiring configuration before installation.

Replacement Guidelines:
Replace the York S1-025-38252-000 when the thermostat fails to initiate a heating call, does not respond accurately to temperature changes, or causes irregular furnace cycling. Replacement may also be necessary if its wiring terminals or internal switching mechanism become damaged. Have a qualified HVAC technician inspect the thermostat wiring and verify heating operation after installation.

Common Signs of Wear:

  • Furnace fails to respond to the temperature setting
  • Heating cycles start or stop inconsistently
  • Thermostat contacts fail to switch
  • Loose or damaged wire connections
  • Physical damage to the thermostat housing

Equipment Compatibility:
The York S1-025-38252-000 Heat Only Thermostat is a genuine OEM replacement part specified for selected York and Coleman heating equipment. Compatible equipment models include EB17A, EB20A, EB23A, DGRM056AUA, DGRM056AUB, DGPH070ABTA, DGPH070ABTA/07-2003, 3500-911/A, and 3500A811.
