Modine 5H71675 Fan Timer Relay for PDP and PV Unit Heaters

The Modine 5H71675 Fan Timer Relay is a genuine OEM replacement component designed for Modine PDP and PV series gas-fired unit heaters. This essential control device manages the timing sequence of the main heater fan during startup and shutdown cycles, ensuring optimal performance and equipment protection.

Key Features:

• Delays main heater fan operation during firing up and shutting off cycles
• Compatible with most Modine PDP and PV power-vented unit heater models
• Genuine Modine OEM part for reliable performance and exact fit
• Replaces discontinued part number 5H71681
• Alternative part number: 5H0716750000

This fan timer relay is a critical component in commercial and industrial heating systems, including those used in warehouses, workshops, garages, and agricultural buildings. The timer relay protects the heat exchanger and extends equipment life by preventing premature fan operation that could cause thermal shock or inefficient heat transfer. Proper fan delay timing also maximizes heating efficiency and reduces energy waste during heating cycles.

Applications: Ideal for Modine PDP Series (power-vented propeller models) and PV Series (power-vented) gas-fired unit heaters ranging from 150,000 to 400,000 BTU/hr capacity. These heaters are commonly found in commercial greenhouses, manufacturing facilities, automotive shops, and large residential spaces requiring efficient overhead heating.
