Description for Honeywell SV9641M4510

3/4 in. NPT x 3/4 in. NPT Intermittent Hot Surface Pilot Ignition SmartValve Control with standard opening and 3.5 in. wc pressure regulator setting

Features

  • These controls communicate directly with an electronic fan timer (ST9160 Electronic Fan Timer for single stage applications; ST9162 Electronic Fan Timer for two-stage applications) in typical forced warm air furnace applications.

  • They also interface with the 208907 Terminal Board, providing compatibility with power stealing thermostats. Or, they directly interface with the appropriate power supplies and a system thermostat for additional appliance applications.

  • When controlled directly by a thermostat, these controls do not provide a postpurge function, because power to the control is removed when the thermostat call for heat ends.

  • The SV9541 and SV9641 Systems are suitable for a wide range of fan-assisted combustion gas-fired appliances including furnaces, rooftop furnaces, boilers, unit heaters, infrared heaters, water heaters and commercial cooking appliances.

                    This was the right part. Just follow the instructions and any DIY can do this change out.
                    I did call a friend in the business to make sure I didn't create a dangerous problem. Saved several
                    hundred dollars over the cost from a local DIY

                          I had a repairman out to look at my furnace and he confirmed my findings that the gas valve was bad, the problem was his part was twice the price of this one I found online and it was a OEM brand. Saved a lot of money, thanks.

                                      I replaced an older Honeywell SmartValve with this newer model, and am quite pleased with the unit.
                                      It was brand new, and installed quite easily, and is currently operational with no problems at this time.
                                      Very satisfied.

                                                  This valve did not work and it needs to be exchanged for another one. This will cost me a couple of weeks to ship back and receive the return unit. Not real happy.

                                                                      I am wondering if the SV9541M4510 is a direct replacement for the SV9541M2094? I see on your list that it says it is. I also see that the SV9541m2094 has 1/2" inlets and outlets. The SV9541M4510 has 3/4" with 1/2" bushings.
                                                                      I replaced my original valve 2 years ago with the original part and am just concerned that this is not a direct replacement and would like a verification.

                                                                      Thanks!

I am in the greenhouse business and use 8 natural gas furnaces so over the years I've learned to make my own repairs. It should take no more than an hour to make the change if there are no complications. My Installation procedure would be as follows (remember I'm no tech.) 1) turn off the gas service going to the furnace. 2) turn of the power going to the furnace. 3) Unplug the two wire harnesses going to the valve making sure you know where they go back. 4) Very carefully remove the gas line connecting the pilot light. then carefully move the line out of your way. 5) disconnect the pipe connecting the valve to the main gas line, hopefully you have a union close to the valve. 6) Now carefully remove the gas valve from the furnace and then remove any of the fittings from the valve you will need to connect the new valve. 7) check all your fittings to be sure they are in good condition. 8) Now you pretty much just need to reverse the procedure to reinstall the new valve. I use tephlon tape on the fittings when I reinstall. This is how I do it. If your not sure about it I would let a repair man do it, remember how expensive the item is your dealing with. Be sure to check for leaks before using the furnace.

This job can be done by a non-pro who feels confident in their abilities in about half an hour or so. You will need adjustable pipe wrenches, sealant tape for use with gas lines (plumbing tape is no good), and some screwdrivers.
                                                                        Don't start this in cold weather if you can't finish it. Your gas supply will be opened and you won't be able to turn it on until its hooked up again.
                                                                        I would start by taking pictures of your valve in place before you start and any connection wires in case of any question later. Turn off gas and electric supply to heater and you can remove the valve. Not much to it. The replacement comes with adapters for supply line size in case they are different. Use sealant tape on threads when putting fittings on. Reconnect wiring and turn power and gas on again. Check for gas leaks and you should be fine.
                                                                        An hour is more than enough time to do this.
                                                                        Again, don't try this if you're unsure, especially in cold weather. Take pictures before you start of everything connected to valve for reference later. If you're not doing this in cold weather give the heater a test run.

I heard that these wires sometimes get dirty and need to be cleaned carefully with sandpaper. After cleaning try the test again the gas should turn on after a few seconds.

                                                                      I have a non-functioning SV9541M2094 on my furnace. Is the SV9641M4510 valve a direct replacement and updated model of the SV9541M2094? I have heard that the 9541 likes to stop working after 5 years or so. So was wondering if the 9641 is more reliable.
