@coldfinger459sub0 5 месяцев назад

@@THExBIGxBADxWOLF93 it good for the simple ones who get over whelmed seen too many things that are spread out . Some students learn better when everything is like on one page in front of them . Have to teach different types of students learning abilities differently. Some students can learn just by reading words without ever seen an actual furnace . Other students literally have to put their hands on the pieces take them off and put them back together before they learn . It all depends on the type of student you are teaching .

Great video! I have a Rheem direct spark ignition unit. The unit would short cycle where the burner would light and burn for about 4 seconds then shut off. After a few attempts, it wouldn't do anything for about an hour. I couldn't call anyone because of my work schedule and it being a holiday week also. I took a shot and ordered a new dual electrode spark ignitor from Amazon, which showed up in only 2 days. After I installed it, my heater works perfectly. Was this just a coincidence or does the spark ignitor have something to do with the flame rectification process? (it was labeled ignitor/flame sensor) Thank you.

@rj.parker Год назад

The only clarification I would offer is flame sensing microamps (ua) is present on the sense wire as well as the ground wire. You need both to complete the circuit.

@chrisdeanndavison3626 Год назад

True, and I believe Craig covered this starting at about 8:00 through 10:00.

@aidanpeluso8350 Год назад

Can you make a video explaining common/neutral wires. What they are, why they are there and what they do?

@takleung7130 Год назад

24V into the ignition module but 120V out to the sense wire. Is there a step-up transformer in the module? Am I missing something?

@pointblankmatt6580 Год назад

i mean it also provides 10000 volts for the ignitor. was curious about this as well. has to be something internal in the ignition control

@MrSnomanjankens Год назад

I had a headache yesterday with a direct spark ignition furnace, except it had a pilot ignition assembly with a single flame rod. The ground wire was hanging on by a thread & was enough to not not give it proper ground. Also the pressure switch was constantly opening and closing since the inducer is on its was out only pulling .67” of WC on a .70” WC switch. The arching from the spark ignition due to the opening/closing of the pressure switch I think may have caused the pilot assembly ground to fail? 🤷

@martini4620 Год назад

A couple months ago we installed a 95% Ruud furnace.It is now rusting very bad , the inside of the inducer collected some orangish rust. Even drain coming out is orange/rusty. Has correct gas pressure. Has both exhaust and intake going outside. RUUD Model # R95TC0701317MSA

@Yeti808 Год назад

Proper duct sizing?

@Kh2456 Год назад

Having issues with my raypak pool heater. I have identified it down to a flame rectification issue as the pilot lights well and doesn’t activate the main gas valve for burners. Today I attempted to test the negative for micro amps (disconnected from gas valve) I connected it in series and couldn’t get a micro amp reading. When unplugging I got electrocuted by touching one probe of the multimeter when the positive was plugged into the negative. Why would the negative be carrying an electrical charge from the motherboard? Thanks

@edwardgarza5104 Год назад

Is there a step up transformer inside that board to be able to send 120 vac to the flame sensor?

@caru3257 Год назад

120v is present at the board and it doesn’t require a step-up transformer.

@RC-Heli835 5 месяцев назад

My old 1986 System does not seem to have a flame rod. It just has the old school honywell intermittent igniter and sparker and the fan limit switch.

@Sightthrough Год назад

I'm curious about the voltage on the flame rod, when we test flame rods in the field we always measure the signal from the rod in Microamps DC, I didn't realize there was also A/C voltage on the flame rod, so the signal from the flame rod to the board is measured in microamps, DC, but the rod also has a potentially high A/C voltage on it? Could you share more about this?

@chrisdeanndavison3626 Год назад

It is flame rectification. I know I'm not explaining this by the book, but basically, the AC voltage present on the flame rod is rectified by the flame to DC. It is just a phenomenon that happens when AC voltage is in a flame. The flame conducts a very small amount of DC current to ground, this is the uA DC that we measure. This is why the ground on a furnace is just as important as the hot and neutral. Also, rusty burners can inhibit the current flow. 14:30 Craig explains this pretty well.

@Sightthrough Год назад

@@chrisdeanndavison3626 Thanks! My fault for posting the question before finishing the video.

@coolramone Год назад

So there are ac micro amps AND dc micro amps running through the flame rod, and which one is being measured by the pc board, ac or dc?

@jynnandtonnyx Год назад

@@coolramone the way I understand it is : there is AC power (different than voltage) available to the flame rod. When the circuit is closed by the flame, the AC power is rectified by the flame to a small DC circuit which can be measured in micro amps. The flame is the switch.

@rj.parker Год назад

@eloy09 Год назад

I was troubleshooting a lochinvar water heater. Same principle though, what happening is it will prepurge and trial for ignition again and again. What should be the problem? No flashes

@Morbidhouse 6 месяцев назад

I'm getting a voltage drop in the MC terminal, when the wire is connected to the gas valve it is only reading 15vac however when it is disconnected from the gas valve it reads 26vac. The pilot is sparking and lighting and blower is turning on however this drop in voltage seems to be preventing the burners from coming on. Would it be the gas valve or the ignition control module at fault?

@Purifiedinfire 6 месяцев назад

My furnace has a control board for everything. The inducer fan goes, the spark ignitor clicks, the gas valve opens in short few second spurts a few times but it won't light. While doing this the furnace clunks or clicks like a gas valve or relay. The best I can gather it's a rusty buner tube not getting ma back to ground or a bad ground and it cutting the gas quickly then retrying a few times before giving up for a few minutes. The part I don't understand is why the clunking or clicking. The furnace doesn't do this all the time just sometimes.

@light0000 8 месяцев назад

Is it possible the flame sensor is bad and wouldnt let my HSI igniter to glow?

@imbobbymuddah 2 месяца назад

What about a faulty module? How can you troubleshoot for that

@user-jp5py6ry7t День назад

When the AC voltage is sent down for the sparking across the the probes(or probe and burner ) to the ground to make the circuit , the flame sensing probe is also sending ac down to the flame to convert to DC for same ground to prove? Is the flame rectification proven after the sparking stops , like a window of time ? As it would be AC from the spark and DC from the flame proving or am I getting confused ? Or is it possible to sense both at the same time from the same ground ? Anyone’s insight is helpful tia

It’s there any please link it to the comment section please n thank

@chrisdeanndavison3626 Год назад

@@mr.spliffaddikts9548 The short answer is no, not really. Most furnaces for the last 30 years do have some sort of onboard diagnostics. When there is a problem, we count blinking lights on the control board and then find the key to what the blinking lights mean to narrow our search for the problem. However, some upper-end units do have more sophisticated means of diagnosing the issue. I service WaterFurnace geothermal units and use an Aid-Tool analyzer on the 3 Series and 5 Series units. Apparently, the 7 Series units can be diagnosed through an internet connection, but I have no direct experience with them. The analyzer can provide a lot of information about how the unit is operating and what issues it might have had or is currently having. Much better than blinking lights.

Flame roll out switch, cannot find a replacement for mine, keeps tripping can you help me find a replacement for it? Thank you

@jimbarron8688 9 месяцев назад

A flame rollout that is constantly tripping is usually a sign of a cracked heat exchanger and is very bad news. These switches are generally very reliable so you'd be fortunate if a replacement solved your issue. A CO detector near the burners when it's running might show high CO as would a washy flame pattern that rolls out when the main blower powers on.
