Replacing hot surface ignitor and flame sensor on Amana furnace
Amana AMH8 furnace, about 3 years old, and when I had the yearly cleaning done this year they suggested to get the hot surface ignitor and flame sensor replaced, but the estimate was about $555 (attached).
I'd like to do it myself, so a
ny suggestions on where to find step by step instructions to do this?
Why, what’s wrong with the current parts?
The flame sensor is nothing but an inanimate object. It’s a metal rod with porcelain. It can be cleaned.
The igniter shouldn’t need replaced unless it’s cracked or otherwise damaged.
Be careful with seasonal PMs, especially with companies your not familiar with. Many times they will use PMs as a sales tactic.
Shouldn’t a 3 year old furnace still have a warranty?
I would not replace parts just for the sake of it. Both items you mentioned are pretty reliable. The ignitor on my furnace lasted 18 years and I've never had to replace the flame sensor.
If you are concerned you can order the replacement parts just so you have them on hand. That way you can replace them if they ever die (since things often die on holiday weekends when you can't get a service person for days). Replacing them is very simple and is just a matter of duplicating what is there already.
R&R of both the HSI and flame sensor are totally DIY-friendly projects. As others have said it sounds like the hvac company is trying to upsell you.
You may want to acquire a HSI and keep it in your inventory because they can fail. If the flame sensor causes trouble it's often because the sensor tip has oxidized: remove it with steel wool and you should be good to go.
I read you should handle these parts while wearing nitrile gloves to prevent transfer of skin oils.
Greetings to all. I am going to replace an old White Rogers standing pilot gas valve that is obsolete,(36B12Z TYPE 201) with a new WR valve 36C03-333. The furnace is an old (1974?) Duo Therm 705001-4 in a mobile home. It is set up for LPG. I can't find any info on it.
I hope that you folks can answer a few questions on the 24V wiring and ECO for the install.
The old valve has only 2 connection spades.
I'm assuming one is TH for thermostat the other TR for 24v. see pics.
So that's where I am going to connect those furnace wires to the new valve as well and not use the TH-TR spade.
The new 36C valve also has 2 extra connections for an ECO where the thermocoupler screws into. According to instructions, If the furnace doesn't have an ECO there's a jumper wire supplied in the box. The furnace has what I think is considered an ECO in a fuse and a fan limit switch. I'm confused. According to the valve instructions, am I supposed to splice into the 24 circuit and connect it to those ECO connections on the new valve and eliminate the fuse? Or should I ignore those? Or should I use the jumper? I've attached some pics of the old furnace and the hookups and new valve instructions.I appreciate any guidance, Thanks.

Quick question, I have installed a couple of ecobee3lite thermostats using the PEK and installing at air handler so have some knowledge. I am installing 2 on a system with a Honeywell HZ311 controller and no C wire. My question is do I need to install a PEK for each thermostat and should that be done on the controller at t=stat connections?
Thanks
