bryant heater, minneapolis-honeywell magnetic valve problem

mgodsey

I have a magnetic valve that has stopped working properly, wasn't completely closing and allowing small amounts of gas into the heating system when not actually running. Seeking advice on finding a replacement. Here are photos and all the specs I can see.
Bryant gas heater (see label attached)
Minneapolis-Honeywell Regulator Company
Magnetic Valve Type
V84C1Dj3 FT
max press 4 OZ
12 Watts
Volts 24
60 Cycles
See photos attached
Looking to repair/replace this valve and get the system running again.
Any advice/help is GREATLY APPRECIATED.
Thank you,
Mark

You'll have to replace it with a modern combination valve that contains the regulator and the safety valve and controls the pilot. You'll need a gas tech to set the combustion properly.

Is the manual knob on the bottom released all the way?

Mattmia2 Thank you for that info. I don't know the first thing about what to order though. All I have to go on is the numbers on the valve. My local heating specialist said it was impossible to find a replacement so I'm trying to find it myself. Do you think I should call carrier/bryant for their suggested replacement part? Anything will help. Thank you again for taking the time. I don't know if the manual knob on the bottom released all the way. As for your question about manual knob... the It looks like something is unscrewed(?) or not tight to the base on the bottom. The gas supply to the furnace is turned off now. should I do something to test that bottom knob? Thanks again.

You need to find a better tech or replace the furnace. The tech that can install a modern valve correctly would have no trouble picking it and the accessories out of a catalog.

I'm $eriously concerned about the co$t of a new furnace. I really want to find someone to identify and place the replacement part.

Hello @mgodsey,
This was not hard to find, for one example. There are others, depending on the pipe size, etc.

Upgrading to a more modern gas valve may gain you more safety features.

You cant just replace that valve, you have to bring it up to modern code if you touch it. Anyone that knows what they're doing can get a standing pilot combination valve and retrofit it. It may need a slow or staged opening valve to light smoothly, they can figure that out by observing the old valve.

Maybe it already meets modern code with other equipment not shown or mentioned.

So "or" does not really mean or.

"Since 1979 all heating gas valves have been required to be dual seated valves or have an ECO back up safety attached to the thermocouple on the valve system. "

It is possible but very unlikely. If someone was going to retrofit it they would have just used a standing pilot combination valve, it is by far the cheapest and simplest way to do it.

That furnace is at least 60-70 years old and very inefficient.

It’s seriously time to look at replacing it.

And yes, someone could modify it to function with a modern combination gas valve and pilot assembly, but by doing so, the certification for the safety of the furnace is voided and whoever would choose to do so would be legally liable for it.

As a licensed HVAC contractor, that’s not something I would even consider.
