Hi, I have a weil mclain boiler that was installed in 2004. It's a LP version and I have two problems: 1) when I take a shower the boiler comes on, runs its cycle and when it hits 4186 the power to it goes off. The screen is dark, the boiler is completely shut down. I have had plumbers and electricians out here, no one knows what is causing this and it will mean I won't have heat or hot water for the winter. 2) there is a leak somewhere in the system, I lose 2-4# ***** a day. I think we'll be able to put a valve on that to refill as necessary. The boiler itself had a maintenance kit put on it last October so it has been maintained. I really need help as I'm out of options for local service people.

I had my Lennox A/C charged on 6/24. It needed 3+ pounds of the older refrigerant since it is about 16 years old. The A/C lines run from the evaporator coil which is above Lennox furnace through the attic above ceiling and out to condenser. About 3 days later, I noticed two areas in the ceiling forming water stains. A/C person said "water line" to A/C froze (this is June and I've had this A/C for 16 years. This has never happened and I live in Denver). A/C person said "they" should never have used copper line and said he would replace it with plastic line. This doesn't make any sense to me at all. He said he "braised" three area where there were leaks. Could overcharging the unit have caused this? Why would this happen after 16 years of surviving winters? Am I missing something?

I have a Trane xr13 that just stopped running. The fan outside is not moving and there is no humming noise. I changed out the filter, it was filthy. I turned off the thermostat and that didn't work. Any ideas?

28 year old Carrier Furnace/AC 58DHB040-111BC. The blower is just humming when I turn it on. 9 months ago, replaced run capacitor to address similar problem and started working again. Now, similar problem but more of a hum when turned on. Had a spare new run capacitor for this model (ordered a spare earlier). Replaced it. No effect - turn on blower motor and it gives off a loud hum, like motor not running.

I have a furnace Thermo Pride Model OD6FA072D48.There seem to have cleaning ports, however, I'm not sure how to use them. There are "flow stoppers" that are in the way for me to introduce a brush or vacuum hose (they have a bolt in the middle to secure the outer cover. Please see pictures. If I try to push them inside they seem to want to fall inside. I can't seem to get them out. Any ideas?Does anybody have a service manual for this?

I want to use my cooling system to reduce humidity in the

I want to use my cooling system to reduce humidity in the house. I have a Trane ser20 system with 2 stage cooling and variable speed blower. I have the prestige IAQ thermostat with red link and the EIM interface. I understand to wire one terminal from U1 to the RH terminal. My question is when it states wire other U1 terminal to low speed fan, do I just wire to terminal G and it will call for low speed fan or do I need to locate the low speed terminal of my fan motor and wire into that? Thanks. Steve

I am looking at a goodman gms80703anaa furnace that's twined

I am looking at a goodman gms80703anaa furnace that's twined to a gms80453anba.I have been looking at a set of install sheets that describe twinning, the instructions talk about twinning for heat modes of single and 2stg, the units have the "twin" terminals on each and from what I can gather the twin terminal operates the fan control in unit two. I see how the first unit 24v is wired as normal and unit two is wired to heat via a isolation relay of w1 of unit 1 to operate w1 of unit 2. So my question the instruction do not talk about AC, other than the twin terminal, is this twin terminal the only requirement to run unit 2 during AC and is this the same for fan on control?The units are wired wrong and miss behaving I want them wired correct and as far as I can see the unit 2 does not require any kind of special isolation relay controls to operate the fan ????
