Description
Product Summary
The McDonnell & Miller 37-27 is a gas valve from McDonnell & Miller, described by the manufacturer as: valve bracket gasket for 51 47 247 USE # 313900 OLD# WAS 312800 (M5).
A gas valve controls the flow of gas to the burner and, on pilot models, to the pilot. It opens only when the ignition system or thermocouple tells it the appliance is ready, regulates the outlet pressure to the burner and closes the moment the call for heat ends or a safety fails. Common signs of a failed gas valve are an igniter or spark that never lights the burner even though the valve receives voltage, a pilot that will not stay lit, manifold pressure that cannot be set, or a burner that keeps firing after the thermostat is satisfied.
Before you order, match 37-27 to the part number on the part you are replacing or in your equipment's repair parts list, and confirm the voltage, size and connections match your equipment. If you are not sure which part your equipment needs, call us at 1.888.509.3391 with the model and serial number and we will confirm it for you.
