Heater Problem

[proshooter]

I have 2- H150fd/n. They both were manufactured in 2014. I bought one on Ebay. It was new ...never installed from a person that bought a "Going out of Bussiness" deal from a pool store. I drove 2.5 hrs there and 2.5 hrs back to pickup the first one. Installed it and couldn't get it to fire up. I took it back and it was replaced with another H150fd/n. For my troubles the seller gave me the first one I returned to use as parts...or fix it. I installed the second one mid-season in 2015. It worked great. Fast forward to the end-season 2016. Heater worked fine all summer until Sept...when we really need it. It would cycle through 4-5 times and then the code IF. I messed with it exchanging every part from heater #2 that I could think of using the trouble shooting guide from Hayward. No luck. I then read this forum and used tape to cover 1/2 of the blower holes as described. Fired right up and runs fine. I'm hoping that the heater #2 has the same problem and can be used by someone. Not sure if this is a long term fix but it works!! Thanks for posting!!!

Could someone post a picture of the holes they covered, please?

I ask because I have an h400idl2 and I don't see these holes.

Hello, Thanks for the tip. I installed a new H400FD today and the install went well but as noted here The flame kept going out. I used your tip and covered 50% of the holes and the flame stayed on and all is well. Thanks

OMG. Was so frustrated til I read this post. Had a probcome out. Had a new meter put on my house. Was about to dig up the gas line! I knew it was all BS! A 6" piece of duct tape fixed it. I'm not very handy but can find the blower and blower plate in the manual. Took my cover off. There it is. A bunch of square holes to let air into the blower motor. IMPORTANT. I FIRST COVERED THE LEFT HALF VERTICALLY AND THE PROBLEM PERSISTED. ONE GUY SAID HE COVERED THE BOTTOM FOUR ROWS... SO I COVERES THE BOTTOM FOUR ROWS WITH THE SAME PIECE OF TAPE... BAM! FIRED UP FIRST TIME AND HASNT SHUT OFF FOR 10 minutes!
Thank you thank you thank you. Please read if you are having Hayward pool heater IF error code problems with the heater staying on.

Did you leave the tape on permanently and did it cause any problems? I just fixed mine with the tape fix.
Thanks

I have a 3 1/2 year old spa-rite gas heater and when I went to check it tonight the SPA & POOL lights were green and my heater won't do anything. I replaced the cognitive 2 weeks ago.
