how do I delete this?

It does sound like you need to replace the gas control, but here are a few other thoughts that might help someone else.

Every one of these I have checked has been grossly overfired out of the box....

I just battled two different units, same model, but a three ton and a four ton.
Both of mine were installed within a year, both giving low pressure lockouts on start up in very cold weather. By the...

Return duct. That's it, the one 6 inch run and the grille in the room with a sooted oil furnace.

Could someone post or send me the service bulletin? I searched but didn't find anything. I had a similar issue early this heating season and could not get it to misbehave while I was there.

Like said above, get the 'Rear Coupling Box' kit, which has the cold spot baffle. Bring a few pop rivets or two scratch awls, to align the face plate, gasket, and heat exchanger cell screw holes.
I...

The worst for me was a a RTU compressor on a very hot day, with a thunderstorm on the way. Weighed in the charge, figured I'd check the data plate one last time before I hit the disconnect... The...

Thanks, I didn't realize I gave detail of the cabinet, not the coil. The coil number is c7bam03036c-b. Has anyone had problems with these blowing water off?

Thanks

Our new neighbor built a modular home with a downflow furnace. Water is dripping out of the duct tee under the furnace.

Does anyone know if this coil is rated for downflow installation?...

I used the Goodman drain pan insulation kit on my own variable speed air handler. It is just foam tape, like I have used on linesets. It cost a bloody fortune for what it is. I still killed a...

It runs. I took the starter to our shop mechanic, who sent it to the rebuild shop. They picked it up, rebuilt it, painted it, and delivered it back to our shop. $42.80, and I am back in business! ...

I would like to think I don't get speeding tickets because I don't drive like a 20 year old anymore. In reality, I think I don't get tickets because I don't look like a 20 year old while speeding...

Its a 5 speed manual, 2005 with the small 4 cylinder engine.

I found the starter, it is clicking when the key is turned. The terminals are too rusty for me to measure voltage at the posts, I need...

I didn't make any more progress today, I got called to work. I'll be working on it after work tomorrow. I don't even know where the starter is on this car. Strange that the first time this car has...

It is not the battery. The charger amps went down to the bottom of the range after a while.

I hear a click, but it doesn't sound like a starter solenoid to me, more like a relay in the dash, but...

I bought a new battery today for our Saturn Vue, It wouldn't turn over, just like the old battery. My first thought was, I mis-diagnosed a bad battery.

I put the battery charger on the brand new...

Automotive analogy: Our shop mechanic likes The Fords better than the Chevys. My cousin, a Chevy guy, says he must have to fix the Fords so much more than the chevys, that he is better at fixing...

Loosen the set screw!

Put a few drops of oil where the set screw goes, then put a Crescent wrench on the flat of the shaft and turn it. Sometimes it will come off, especially if you clean the...

My most was 99.5 hours, a week on call in January. I Have not been over 80 in a long time.

I think I make as much in a 40 hr week as I did in that long week, years ago.

My method, sniff around with the leak detector. Run the system, expect a little bit lower temperature drop, maybe 15 instead of 20. With no history of leaking, no leaks found, and a respectable...

The flame sensor is wired to the neutral side of the ignitor, so it is always connected to the board's flame current circuit.
There are not many of those old Rheems left in my area. They would have...

Glennac, where are you buying Methanol? I was recently looking for some for de-icing a regulator, and I struck out. I don't want to buy 35 gallons, just a quart or two.

Thanks for the input. I will try those and report back

I was chosen as the tester, to see how useful an iPad is to service techs. I am looking for a photo editor that will let me write on a picture, then email it. I think it would be nice for furnace...

Un-cased coil, with a little panning. It was a 100,000 BTUH Goodman in a 50,000 BTUH house. The coil was too narrow, but it was in stock, I guess. I also got a good video of the flame rollout....

Chimney liners, reducers, mortar... who needs them?

Tenant: Furnace is in the basement, you'll see it.
I itemized every piece of junk I had to move to get to the furnace. Turns out, the tenants ripped down the vinyl tube from the condensate pump. ...

I never saw this before. The pressure reducing valve failed and overfed. The relief valve failed and didn't open. I saw 50 psi, who knows what it was when it was firing. Customer came home to...

A few pics from this fall.
If you can't get the secondary pan level, put the float on the high side. It keeps the float dry, so it lasts longer. The customer knew there was a problem when it...

I was asked to install a customer-purchased part, a pilot assembly, with thermocouple and powerpile. She had fought lighting the pilot for a month, then bought the part mail order.
The new parts do...

Stupid thread, I can't believe I read it.
Can we debate if a dirty filter will make a limit trip, now? It is heating season in some of the country.

I started in this trade at a York dealer that had a few Triathalons out there, just as they were failing and being withdrawn. They all had been installed at gas company bigwigs' houses, with some...

He is right. Our customers will gladly wait a little while for a call back, the others will keep dialing down the phone book. A tip off is when they ask "Which company are you with?" Which company...

None of our neighbors have cell phones. They won't let me take their pictures either, so I set up to avoid getting David or his kids.
Its interesting how the "rules" change area to area. When...

It was my second time there, it has a two year evaporator leak. My back started hurting when I heard her name. I only went because I figured this time she would buy a new one. When I heard about...

I got to help make hay with our neighbor yesterday. He's Amish, so he does it a bit different then most people. He hays his farm and ours, and feeds his stock and ours with it.
The hay was cut two...

She said I muttered under my breath about working on her unit. Also said I made her feel guilty about not replacing her system. She couldn't afford a new unit because she just got home from 3 weeks...

In the garden, I use a hoe. A hoe sharpened with a file, and angled parallel to the ground works great and is no great physical workout.

Where practical, I use mulch. I mulched the squash,...

Here are the tractors in question, but the question also applies to RTU blowers.

Most outrageous mechanical room story I remember, an on call tech at a market reefer company got calls to the boss from two stores in two days. One store manager saw beer cans fall out of his truck...

Our installers made a tool for hole sawing SpacePak outlets in nice houses that may help sometimes. They use a clear plastic bucket, the square ones nails and screws come in. One small hole in the...

He said she was undercharged, added gas. You said she was undercharged, didn't add gas. Nobody did a leak search! I would have found the leak before I told her she was low. Fixing the leak is the...

Just do it. You won't have much time or money invested. I wouldn't bother with permission from the King. Live your life. I doubt your neighbors will complain, they'll probably join you in an...

That is the kind if job I envision when a commercial guy comes on here and asks for help on a side job 'for my buddy.' They look down their noses at residential guys, still.
