Push the connection nut to the threaded connection where the copper lead connects to the gas line. Ca. If LP gas is used, then manifold tube has reverse threads. jeremytl Scientist Joined: Jan 17, 2007 Occupation: scientist Location: durham, nc I replaced the thermocouple.
To make necessary bends to route the thermocouple into position between the pilot-sensing end and its screw-in connection to the gas valve, use the bending template in the installation instructions. The system returned: (22) Invalid argument The remote host or network may be down. Everyone seems to have had trouble with the the Unitrol gas valves for awhile (including Rheem and others...BW had the same set up for awhile, but they have far fewer installed.) Common Thermocouple Problems This feature is not available right now.
Anyway, glad you could repair it--it is beyond the ability of some folks. Thermocouple Testing Procedure ISO 9001:2008 Registered Questions? Carefully complete a thorough inspection of the thermocouple probe looking for any pin holes, cracks, and areas with discoloration indicating internal contamination issues. https://highperformancehvac.com/how-test-thermocouple-multi-meter/ My Account Login Live Support About Temprel Our History Company Brochure Terms & Conditions Warranty Services Custom Applications Calibration Repair or Replace Services Technical Training Tech Support What is a Thermocouple?
In summary, it is strongly recommend that you work with version ≥ 1.4.1 of the instruNet software, and that AUTO CAL RATE be set to approximately 5 minutes and CJC CAL How To Tell If A Thermocouple Is Bad The wiring should also be inspected, as contamination on the surface of the wire can greatly reduce the accuracy of the temperature. Those devices generally will not use a thermocouple.

A thermocouple is an electrical device that responds to temperature change by a change in voltage output. The pilot light is a small open flame that is fed by a steady flow of gas. In general the TC should be grounded at one place. Source If you are on the ±80mV range and want more accuracy, try the ±20mV range.
Carson, Dunlop & Associates Ltd., 120 Carlton Street Suite 407, Toronto ON M5A 4K2. Thermocouple Failure Symptoms Rheem/GE/ Richmond water heaters have TRD instead of TCO. Watch out: If any gas connections were removed and replaced (usually not necessary if you are only replacing a thermocouple) then check for leaks using a chloride-free soap and water solution.
Typically the thermocouple sensor is mounted right in the flame of the pilot light on gas fired heating equipment.
Typical multimeter will work/ might not have alligator clips. The pilot flame must intersect the thermocouple for it to genereate the signal to tell the gas valve it's okay to light. And I would not advise using a battery to test the valve. Troubleshooting Thermocouples You should not see any bubbles.
To replace a thermocouple: Step 1: Unscrew the copper lead and the connection nut inside the threaded connection to the gas line. I've occasionally had trouble with a thermocouple that seemed connected to the control but wasn't perfectly seated. And no, there is no fee for my consulting as long as it doesn't become too consuming for me. Green links show where you are. © Copyright 2015 InspectApedia.com, All Rights Reserved.
If pilot is going out, then clean air intake and get more fresh air to water heater to see if problem is solved. 3) Thermocouple must sit in the pilot flame If the reading on the computer screen changes, this means that RFI is interacting with your wires since changing the EMF flux through the wire loop changes the voltage at the Thermocouples (INC) Thermocouples should always be stored at room temperature, in a non-humid environment and sealed in a (Air Tight) bag in order to prevent moisture from causing contamination, should long For example do not try to cut or trim the length of the thermocouple.
Air Conditioning and heating preventive maintenance also pays for itself by making the unit more efficient, safe, and reliable. You will here a "snap" or "click" soundwhen the magnet opens, if you hear this sound prior to a drop of 6 millivolts, the magnet is out ofspecification and the combination Valves are not repairable.

After setpoint temperature is satisfied, the gas control is shut down, and power removed from relay. This planet needs more geniuses like you around.
Question: flame doesn't thouch the thermocouple (Oct 15, 2015) Frank Guttery said: Pilot flame does not touch thermocouple all the time. Here are some diagnostic questions: Over what time have how many thermocouples failed? Some gas fired heating equipment relies on an electronic ignition to ignite the flame. TERMINAL CONNECTIONS?
Loading... From what I've seen personally and other posts here, the replacements seem to be holding up. Advertisement Autoplay When autoplay is enabled, a suggested video will automatically play next. On these appliances there may still be a thermocouple to confirm that there is a good gas flame when the burner is on - since we don't want to continue supplying
