Review: Works as it should! - Worked as it should and saved me from paying $900 for the furnace guy to do it! The hookup is super easy, just need a screwdriver.
Review: Great working part - I work on some really old heaters and use these to replace the “black box” sequencers and individual old stuff. These are much easier and safer to use and are cost efficient. I have used them for years as retrofit for the older models and have never had issues or problems yet and have not had to replace one yet. They’re a good product.

### ⭐⭐⭐⭐ update on my prior review
*by D***S on January 31, 2019*

for now, i am happy i bought this sequencer. long story short, i needed a sequencer with 3 switches for an old lennox furnace that originally had three separate relays for each of the three elements. i have a 1970's vintage furnace and in the past 30 years all i've had to do to keep it running is to replace some wiring and also periodically replace the sequencer. my old sequencer finally failed and one switch was stuck closed, so i had a runaway furnace to deal with that could only be turned off from the breaker. since about 2000 when i started keeping track, this is perhaps the third or fourth time i've had to replace the sequencer. each one seems to last a few years, plus or minus. i used to be able to get a replacement from a local shop, but new ownership requires that they send a tech out rather than sell to the public. ugh. the item i received was a ningbo yuanfang sequencer, and not an emerson t-o-d as shown in the advertised pic when i ordered it, for $16.05 last month. these sequencers have a limited life. we'll see how long this one lasts. for now, i am going to order another so i have it on hand. price is reasonable. but, as i have discovered in the last few days, the offers on amazon can change quickly, in terms of suppliers and prices.
