Hi I have a York heat pump & last Saturday I had a message on my thermostat screen that read "Outdoor equipment fault". I took a pic & added it. Today I logged into the service mode & there were 2 outdoor equipment events listed from last Saturday. I took a picture of log & both events that were listed from Saturday & added them as attachments. The temperature in my house is staying where I have it set but I do not know if the heat is coming from the outdoor heat pump or maybe just the auxiliary heat coils in the inside unit. Any suggestions & or ideas on what the 2 Saturday events mean? Thanks [attach]98784[/attach] [attach]98785[/attach] [attach]98834[/attach] [attach]98835[/attach]

First of all, I am a novice. Please forgive my limited understanding. However, I have been researching my issue for the past week or so. I thought I found the issue of my weak heat (the sequencer), but after install of a new sequencer today, I am not so sure. The issue: heat pump heat works, but cannot heat the house adequately on colder nights/days. In emergency heat mode, heat does not increase but the fan kicks on as normal. Weak heat from pump only. This is a dual heat strip system, two 5kw for 10kw total. I figured it was the heat strips not turning on. First, I checked all the connections of the wires to the sequencer and temp limiters. I turned the system back on, and to my surprise, I had very hot (100+f) air from vents. I was so happy because I thought it was just a loose connection somewhere. However, when I turned off the system at the thermostat, nothing happened, the heat and fan stayed on even in off position. A quick tap with a handle of a driver to the sequencer shut it off (like fonzie). I thought, of course, the sequencer was bad. I ordered a new one and installed it today. However, now it has returned to the original state, weak heat without strips turning on. I triple-checked all connections are the same as before and am confident about that. Trying to test the new sequencer, I got a multimeter at my local hardware store, although, I don't really know what I'm doing. When testing the new sequencer, the back two connector terminals, my multimeter beeps, indicating an open circuit (I think?). Is this normal? I watched a video of someone testing a sequencer and they knew it was bad when it beeped. I am sorry for the long post and lack of knowledge, thank you for reading. Could anyone help me to determine if, in fact, my new sequencer is bad? I was pretty sure the symptoms before indicated it was bad. But the wiring must be correct because the heat strips kicked on before. Is there anything else I can try? Here are photos: 1) The broken sequencer, which worked (stuck open heat), and fell apart when I took it out. 2) New sequencer installed, but not turning on heat strips and multimeter beeps when connecting top and bottom back (gold) terminals
