Within a couple of days of getting the pilot lit we noticed that he AGA didn’t have the frequently described “gentle radiating heat” but rather a fierce intense heat and an odd smell. It turns out we had a gas leak. One of the obsolete parts, the Mag Valve or Safety valve of the Mk 1 Teddington, was toast, i.e. leaking. The technician who installed the oven walked me through the diagnosis (he is 4 hrs away) and sent me a used spare part to install. A few hours of fiddling about with wrenches and pipe dope or thread sealant, and we were back up and running. Now we have that gentle radiating heat and it runs much more quiet.
Things we learned:
- If you smell what you think is gas, it probably is. Spray some soapy water on the pipes, if you see bubbles form that are the size of quarters, you found your leak.
- A replace ment for the Mk1 Teddington cost about $1600 to $2500, installed by a technician.
- agafixspares.com, located in the UK, sells the replacement burners for 595 GBP plus another 80-100 quid for shipping.
- The replacement burners are on backorder.
- agafixspares.com just received their first order of Oilwarm replacements for the Mk1 Teddington. These look very similar to the AGA version. They are 575 GBP but most importantly, they are in stock (or more readily available).
- If you are in the market for a used AGA make sure you know your burners. Study up and make sure you get a late model. Despite their appearances, not all AGAs are equal.
