True 801849 Genuine OEM Drain Tube Heater 115V 10W

True 801849 Genuine OEM Drain Tube Heater

The True 801849 Genuine OEM Drain Tube Heater is designed to help prevent condensate drain tubes from freezing in select True commercial refrigeration equipment. During normal refrigeration operation, moisture created by the evaporator must flow freely through the drain system. This heater helps keep the drain tube above freezing so condensate can drain properly instead of forming ice blockages.

This Genuine OEM heater is rated at 115 volts and 10 watts with an approximately 32-inch heater length, 50-inch leads, and a 1/2-inch stripped wire end. Using the correct OEM drain heater helps maintain reliable condensate drainage and supports normal refrigeration performance. 

How the True 801849 Drain Tube Heater Works

During refrigeration and defrost cycles, condensate water must travel through the evaporator drain system. Low temperatures can cause moisture inside the drain tube to freeze, restricting water flow and creating ice blockages.

The True 801849 heater provides low-wattage heat directly to the drain tube, helping prevent ice formation while allowing condensate to flow normally.

When operating correctly, this heater helps:

• Prevent frozen drain tubes
• Support proper condensate drainage
• Reduce standing water inside the cabinet
• Help prevent evaporator drain ice buildup
• Support reliable refrigeration performance
• Reduce unnecessary service calls caused by frozen drains

Common Symptoms of a Failed Drain Tube Heater

• Frozen evaporator drain tube
• Water overflowing inside the cabinet
• Ice buildup around the drain opening
• Water leaking onto the floor
• Drain pan overflowing
• Repeated drain freeze-ups after defrost cycles
• Excess moisture inside the refrigerated cabinet

These symptoms may also be caused by clogged drain tubing, damaged drain pans, improper equipment leveling, or restricted condensate flow. Inspect the complete drain system before replacing electrical components.

Why Replacing a Failed Drain Heater Matters

A frozen drain tube can prevent condensate from draining properly. When water cannot leave the evaporator compartment, it may freeze, overflow, or leak into other areas of the cabinet, increasing maintenance requirements and reducing equipment reliability.

Replacing a failed drain heater helps restore proper condensate drainage while reducing unnecessary ice accumulation and water-related service issues.
