Dull Men's Club
An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine or advice forum.
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions, identify objects or get advice. We accept very few questions, and they must be over topics much more difficult than what is easily discoverable with a search. Also see rule 1, “comment baiting”.
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. Not hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.
8. All polls must have an "Africa, by Toto" option. Why? Because we hear the drums echoing tonight.

Short cycle probably isn't the control board. More like something isn't working right (sense unit for flame, pressure switch for evacuator blower, etc).
Furnaces are fairly simple (at least in number of components), and the board will flash an indication of the error. Pull the cover off and look at the diagram on it - there should be a chart showing how to read the flashes.
Side note: it's probably been short cycling it's whole life, since most are way oversized, and installers don't bother to adjust the ductwork/dampers or the blower speed. Most likely the blower is configured for max speed, and it would work better at low speed.
Everywhere I've lived this has been the case, and configuring the blower to low speed worked fine, and the air conditioning actually worked better (too high of a speed and the air exchange rate is too high to dehumidify the air properly).
