Product Highlights
Description
A replacement heat motor assembly used in Bell & Gossett Comfort-Trol zone valves to drive valve operation for hydronic heating zone control.
Key Features:
- Replacement heat motor assembly for Comfort-Trol zone valves
- Q&A notes on identifying a failing/failed motor (field indicators mentioned by respondents):
- Some reference checking the back of the motor for a copper-colored area/indicator
- Some note the motor's black coating may show change/discoloration when overheated
- Some describe failure symptoms as the motor "burning out" or no longer driving the valve
Compatibility & Applications:
- Intended for Bell & Gossett Comfort-Trol zone valve applications where this motor assembly is specified
- Q&A confirms: 189137 is the replacement for V01370
- Must only be used where the manufacturer specifies this exact part number: 189137
Installation & Operation Notes:
- Installation should be performed by a qualified hydronic/heating technician
- Reference the zone valve/control's service/installation manual for the correct replacement procedure and system shutdown/safety steps (the provided sources do not include step-by-step installation instructions)
Maintenance & Troubleshooting:
- Common replacement reason described in reviews/Q&A: the heat motor fails/burns out, leading to the valve not operating correctly and the zone not heating as expected
- Q&A suggests there isn't a single "foolproof" visual test, but points to physical signs (above) and operational symptoms (valve not opening/zone not heating) as common indicators for replacement
User Reviews & Q&A Summary:
- Reviews are mostly positive and frequently describe it as the exact part needed and a successful repair to restore zoning/heat.
- A repeated real-world theme is longevity variation:
- Some reviewers report long service life before replacement
- At least one reviewer reports repeated replacements over time and describes it as "not built to last"
- Q&A themes focus on:
- How to tell if the heat motor is bad (visual/condition clues and symptom-based diagnosis)
- Cross-reference confirmation that 189137 replaces V01370

2 QuestionsQ: Is there someway to tell (appearance, etc) if the heat motor assembly is bad or if might be the entire control valve motor?

There is no foolproof way to tell, but there are three things that could tell if the heat motor is bad. 1. If there is wax that came out of the heat motor. This means the seal is shot and the wax has leaked out and the unit needs to be replaces. 2. If there is discoloration on the back (the one opposite the push rod) indicated a high temperature burn-out. 3. If the heat motor is cold even though there is electricity going to the unit (thermostat is calling for heat). The heat motors will eventually go on these units. A more common problem is pitting of the contacts of the spring switches, preventing the electricity from activating the heat motor in the first place. These contacts can be cleaned with 400 grit emory paper and the tension on the springs checked. It is a pain to do and involved disassembly of the switch. After dealing with this for over ten years, I switched over to the Honeywell valves. The Control-valve units became harder and harder keep going. I have a seven zone valve system, so the switch-over was costly but worth it. We go away for several weeks at a time during the winter, and I didn't want to worry about a loss of heat. Phil Sanzone
When the Heater Motor burns out or fails the back of it is "Black" and not the original "Copper" color. I replace several VO1370 Heat Motors a season! Donald L. Johnson JOHNSON & HELLEKSON REAL ESTATE, LLC 200 E. Main St., Ste. 100 Watertown, WI 53094 ***.****el.
The black coating on this motor will sometimes melt if the motor is bad. Look for signs of overheating. Sometimes a blackish plastic looking material will form at the smaller end. This also indicates overheating and burnout. I've found that you must check the points on the controller for proper function. The points should make the controller cycle between on and off. If the motor stays on, It will surely burn out. I hope this helps.
Yes on the back of the motor there is a copper disk and all the ones I have replaced it is burnt
Q: Is this a B&G P# VO1370?
